Dans son discours de jeudi, lors de sa prestation de serment pour un huitième mandat, le président camerounais Paul Biya a appelé ses adversaires politiques à « l'union sacrée », mais a accusé certains politiciens d'être « irresponsables » et a assuré que « l'ordre règnera ». Comment pourrait se matérialiser cette « union sacrée » ? Quelle peut être, à présent, la stratégie de son principal adversaire, Issa Tchiroma ? Armand Leka Essomba enseigne la sociologie à Yaoundé 1 et dirige le Laboratoire camerounais d'études et de recherches sur les sociétés contemporaines. Il est l'invité de Christophe Boisbouvier. RFI : Dans le résultat officiel de la présidentielle, Paul Biya perd quatorze points par rapport à 2018. Est-ce à dire que son parti RDPC traverse un passage à vide ? Armand Leka Essomba : Je pense que cela est évident dans la mesure où on doit pouvoir reconnaître que le parti au pouvoir traverse effectivement une phase de grande perturbation et que probablement soit ce parti, ou alors celui qui l'incarne a perdu probablement une grande part de son attractivité et de son charisme d'antan. Quand l'archevêque de Douala, Mgr Kleda, dit que le résultat officiel de cette présidentielle n'est pas crédible, est-ce qu'il reflète l'opinion de beaucoup de Camerounais ? Disons que ces suspicions, naturellement, sont d'autant plus alimentées que nous sommes à l'ère des réseaux sociaux. Nous avons eu un temps long [entre le jour du vote et le jour des résultats]. La durée des deux semaines, c'est surtout l'injonction qui est faite à tout le monde de ne point communiquer, ni les tendances, etc. Et donc ça jette parfois de la suspicion. La percée d'Issa Tchiroma, même dans les résultats officiels, dans la région du nord et dans les deux régions de l'ouest et du littoral, c'est-à-dire à Douala, quels enseignements vous en tirez ? L'habileté tactique du candidat Issa Tchiroma aura été effectivement d'incarner, à défaut ou par défaut, disons, la synthèse de toutes ces frustrations. Ce d'autant plus qu'un discours social à connotation, j'allais presque dire métaphysique, circulait pour dire qu'il s'agit de transformer cette élection en un référendum pour ou contre Paul Biya. Et finalement, ce qui se révèle, c'est le niveau d'exaspération. Des gens sont prêts tout à fait à dealer avec n'importe qui, à condition qu'ils mettent à la retraite le président dans son exceptionnelle longévité politique. Issa Tchiroma affirme aujourd'hui qu'il y a désormais deux présidents : le président élu, qu'il est lui-même, et le président nommé par le Conseil constitutionnel, c'est-à-dire Paul Biya. Est-ce qu'on va vers un Cameroun coupé en deux ? Ce que je peux dire, c'est d'exprimer quelque peu mon scepticisme. Il est évident que pendant les jours qui viennent, les moments de tension persisteront, notamment dans certaines des régions qui sont des fiefs du candidat Issa Tchiroma. Tout dépendra aussi des mesures importantes qui vont être prises. Donc les mesures d'apaisement, puisque le président de la République, Paul Biya, a demandé à ce qu'une union sacrée se fasse. Il a explicitement fait mention d'une union sacrée. J'ignore si on ira vers des expériences institutionnelles de large ouverture ou d'union nationale, en termes de structuration, par exemple, d'un nouveau gouvernement, mais les jours qui viennent, il faudra être absolument attentif à la manière dont on pourra traduire les propos assez apaisants du chef de l'Etat dans la pratique et dans les orientations politiques. Tout dépendra de ce qui se fera, notamment en termes de gestes d'apaisement, si l'on se réfère au discour d'hier. Et donc l'atmosphère dépendra beaucoup de la traduction politique de cet apaisement. Dans les années 90, Paul Biya avait déjà affronté un adversaire coriace qui proclamait sa victoire et qui organisait des journées ville morte, c'était John Fru Ndi. Et à la fin, c'est Paul Biya qui avait pris le dessus. Est-ce que vous pensez que le même scénario va se reproduire ? Alors personne n'est en mesure de dire ce qui va se passer demain ou après-demain. Mais il est évident que les contextes ont changé. En 1992, Paul Biya était en effet au pouvoir depuis dix ans, il y avait une certaine vitalité humaine et physique. Il faut en tenir compte. La longévité exceptionnelle au pouvoir crée des dynamiques d'inertie systémique et la fragilité physique et humaine, qui est quelque chose de tout à fait naturel, s'associent parfois pour interférer sur, disons la réactivité institutionnelle. S'installent dès lors des formes de paresse, de lenteur, qui peuvent conduire à des expériences d'immobilisme qui sont tout à fait dommageables. Et peut-être dans sa stratégie, Issa Tchiroma compte-t-il sur un essoufflement du parti au pouvoir et de son président ? Alors je crois qu'il y a derrière effectivement un certain imaginaire dans la stratégie d'un certain nombre des challengers de Paul Biya. L'idée que finalement quelque chose pourrait se passer, qu'un accident pourrait survenir et créer les conditions effectivement d'une transition.

Perturbation theory remains one of the main tools in physics, in particular in quantum theories. However, most perturbative series diverge factorially, and it is not obvious how to extract information from them. Their divergence also suggests that, in order to obtain accurate results, one might need additional non-perturbative information. The theory of resurgence has been proposed as a general framework to address these issues. In this talk I will give an introduction to this theory and will illustrate it with applications -old and new- in quantum mechanics, quantum field theory and string theory.

Il y a 5 ans, la mobilisation des Gilets jaunes traversait la France et la Belgique. Né sur internet et les ronds-points, le mouvement a rassemblé des centaines de milliers de personnes, durant près d'un an. « Colère noire, Gilet jaune », le slogan, témoigne d'une colère inédite face à la hausse du prix du carburant, à la vie chère et aux fins de mois difficiles. Perturbation de l'espace public, blocage des routes, utilisation de Facebook… Le mode d'action et de fonctionnement de ce mouvement protéiforme déconcerte. Et les journalistes ne sont pas en reste. Le saccage de l'Arc de Triomphe à Paris en décembre 2018 sera un choc immense, tout comme la violence policière et les blessures graves engendrées par l'usage des armes sublétales lors de ces épisodes de protestations. Que retenir du mouvement des Gilets jaunes ? Quelles étaient les revendications de ces manifestants d'un nouveau genre ? Et comment tout ceci a-t-il commencé ? Hélène Maquet et Bertrand Henne vous proposent un épisode foisonnant au cœur de la mobilisations des Gilets jaunes, en compagnie de leurs invités : Marc Zune, professeur de sociologie à l'UCLouvain et Arnaud Mercier, professeur en sciences de l'information et de la communication à l'université Paris-Panthéon-Assas.

Le changement climatique affecte notre planète de plusieurs façons. Voici quelques-uns des effets les plus importants: 1. Augmentation de la température: Le changement climatique provoque une augmentation de la température moyenne de la Terre. Cela entraîne des vagues de chaleur plus fréquentes et plus intenses, ce qui peut avoir des conséquences graves pour la santé humaine, les écosystèmes et l'agriculture. 2. Fonte des glaciers et des calottes glaciaires: En raison de l'augmentation des températures, les glaciers et les calottes glaciaires fondent à un rythme alarmant. Cela entraîne une augmentation du niveau de la mer, ce qui menace les zones côtières et les îles basses. 3. Perturbation des écosystèmes: Le changement climatique perturbe les écosystèmes naturels en modifiant les régimes de précipitations et en altérant les habitats des espèces. Cela peut entraîner la disparition d'espèces animales et végétales, ainsi que des perturbations dans les chaînes alimentaires. 4. Événements météorologiques extrêmes: Le changement climatique est responsable de l'augmentation de la fréquence et de l'intensité des événements météorologiques extrêmes tels que les ouragans, les tempêtes, les inondations et les sécheresses. Ces phénomènes peuvent causer des dégâts considérables aux infrastructures, à l'agriculture et aux communautés. 5. Acidification des océans: L'augmentation des émissions de dioxyde de carbone dans l'atmosphère entraîne une augmentation de l'acidité des océans. Cela a des conséquences néfastes sur les récifs coralliens, les coquillages et d'autres organismes marins sensibles à l'acidité. 6. Augmentation des maladies: Le changement climatique favorise la propagation de maladies transmises par les moustiques, les tiques et d'autres vecteurs. Les maladies telles que le paludisme, la dengue et la maladie de Lyme sont devenues plus prévalentes dans de nombreuses régions du monde en raison des conditions climatiques favorables à ces vecteurs. Il est important de noter que ces effets ne sont pas exhaustifs et que le changement climatique peut avoir d'autres conséquences sur notre planète. --- Send in a voice message: https://podcasters.spotify.com/pod/show/chatgpt20/message

Abstract: Perturbations in fundamental developmental pathways have a profound influence on tumorigenesis. Numb plays a pivotal role in vertebrate development, including neurogenesis and is a key negative regulator of Notch signaling. Perturbation of Numb expression affects brain morphology and cell fate. While extensive research has been conducted on canonical Notch ligands, regulation by vertebrate-specific non-canonical ligands is not understood. Here we identify Delta like non-canonical Notch ligand 2/EGFL9 (Dlk2) as a regulator of zebrafish neurogenesis with mutants exhibiting early increase and subsequent depletion of neural stem cells, decreased radial glial cells density, impaired neuronal cell distribution, and hypersensitivity to stimuli mimicking the embryonic murine Numb/Numblike null phenotype. Numb function is inactivated by aberrant phosphorylation, and we show that Dlk2 protein exhibits a high affinity direct interaction with Numb, with loss of Dlk2 in zebrafish telencephalon increasing Numb Ser276 phosphorylation with a concomitant increase in Notch signaling. Patients with tumors exhibiting reduced levels of Dlk2 have a poorer prognosis, while overexpression of Dlk2 in human cancer cell lines reduces cell proliferation. Our findings identify Dlk2 as a key partner of Numb, a gatekeeper of its activity, and an important player in a network of protein interactions regulating both neurogenesis and cancer with potential therapeutic implications.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.07.17.549269v1?rss=1 Authors: Dagnino, P. C., Escrichs, A., Lopez-Gonzalez, A., Gosseries, O., Annen, J., Sanz Perl, Y., L. Kringelbch, M., Laureys, S., Deco, G. Abstract: A fundamental challenge in neuroscience is accurately defining brain states and predicting how and where to perturb the brain to force a transition. The ability to promote a transition from one brain state to another by externally driven stimulation could significantly impact rehabilitation and treatments for patients suffering from complex brain injury cases. Thus, it is crucial to find therapeutic interventions able to re-balance the dynamics of brain disorders towards more healthy regimes. Here, we investigated resting-state fMRI data of patients suffering from disorders of consciousness (DoC) after coma (minimally conscious and unresponsive wakefulness states) and healthy controls. We applied model-free and model-based approaches to help elucidate the underlying brain mechanisms of patients with DoC. The model-free approach allowed us to characterize brain states in DoC and healthy controls as a probabilistic metastable substate (PMS) space. The PMS of each group was characterized by a repertoire of unique patterns (i.e., metastable substates) with different probabilities of occurrence. In the model-based approach, we adjusted the PMS of each DoC group to a causal whole-brain model. This allowed us to explore optimal strategies for promoting a transition to the PMS of the control group by applying off-line in silico probing. Furthermore, this approach enabled us to evaluate the impact of all possible local perturbations in terms of their global effects and sensitivity to stimulation, which is a biomarker providing a deeper understanding of the mechanisms underlying DoC. Our results show that transitions from DoC to more healthy regimes were obtained in a synchronous protocol, in which areas from the motor and subcortical networks were the most sensitive to perturbation. This motivates further work to continue understanding brain function and treatments of disorders of consciousness by external stimulation. Copy rights belong to original authors.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.07.03.547526v1?rss=1 Authors: Kandemir, G., Wilhelm, S., Axmacher, N., Akyurek, E. Abstract: The neural mechanisms by which information is maintained in working memory are challenging to study, as such maintenance is not always correlated with detectable sustained neural activity. Perturbation of the memory network with a visual impulse has proven useful to probe memoranda in such activity-quiescent states. However, the impulse perturbation approach has so far been applied exclusively to spatially localized or spatially referenced stimuli, such as orientations or tone frequencies. It is unknown whether the neural maintenance mechanisms of non-spatial memoranda would be analogous. In the present study we therefore applied the impulse perturbation method to working memory for colours, which are intrinsically non-spatial stimuli, focusing on a set of pre-registered analyses. We analysed the EEG data of 30 participants who completed a delayed match-to-sample working memory task, in which one of the two items that were presented was retro-cued as task-relevant. We assessed the colour space underlying memory maintenance, and found that both cued and uncued colours were decodable from impulse-evoked activity, the latter in contrast to previous reports of working memory for orientation gratings. We furthermore examined colour decoding from ongoing oscillations in the alpha band, and found that cued items could be decoded therein, whereas uncued items could not, which might be mediated by attention. Overall, the outcomes suggest that subtle differences exist between the representation of colours and that of stimuli with spatial properties, but the present results also demonstrate that regardless of their specific neural state, both are accessible through visual impulse perturbation.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.06.22.546199v1?rss=1 Authors: Soetedjo, R., Horwitz, G. Abstract: Internal models are essential for the production of accurate movements. The accuracy of saccadic eye movements is thought to be mediated by an internal model of orbital mechanics encoded in the cerebellum. The cerebellum may also be part of a feedback loop that predicts the displacement of the eye in real time and compares the predicted displacement to the desired displacement command to ensure that saccades land on target. To investigate the role of the cerebellum in these two aspects of saccade production, we delivered saccade-triggered light pulses to channelrhodopsin-2-expressing Purkinje cells in the oculomotor vermis (OMV) of two macaque monkeys. Light pulses delivered during the acceleration phase slowed the deceleration phase of ipsiversive saccades. The long latency of these effects, and their scaling with light pulse duration, are consistent with an integration of neural signals downstream of the stimulation. In contrast, light pulses delivered during contraversive saccades reduced saccade velocity at a short latency (~6 ms) that was followed by a compensatory reacceleration which caused gaze to land near or on the target. We conclude that the contribution of the OMV to saccade control depends on saccade direction; the ipsilateral OMV is part of a forward model that predicts eye displacement, whereas the contralateral OMV is part of an inverse model that creates the force required to move the eyes accurately.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2023.04.23.537976v1?rss=1 Authors: Vranic-Peters, M. J., O'brien, P., Seneviratne, U., Reynolds, A., Lai, A., Grayden, D. B., Cook, M., Peterson, A. Abstract: Studying states and state transitions in the brain is challenging due to the nonlinear, complex dynamics present. In this research, we analyse the brain's response to non-invasive perturbations. Perturbation techniques offer a powerful method for studying complex dynamics, though their translation to human brain data is under-explored. This method involves applying small inputs, in this case via photic stimulation, to a system and measuring its response. Sensitivity to perturbations can forewarn a state transition, therefore biomarkers of the brain's perturbation response or 'cortical excitability' could be used to indicate seizure transitions. However, perturbing the brain often involves invasive intracranial surgeries or expensive equipment as in transcranial magnetic stimulation (TMS) which is only accessible to a minority of patient groups, or animal model studies. Photic stimulation is a widely used diagnostic technique in epilepsy that can be used as a non-invasive perturbation paradigm to probe brain dynamics during routine electroencephalography (EEG) studies in humans. This involves changing the frequency of strobing light, sometimes triggering a photo-paroxysmal response (PPR), which is an electrographic event that can be studied as a state transition to a seizure state. We investigate alterations in the response to these perturbations in patients with genetic generalised epilepsy (GGE), with (n=10) and without (n=10) PPR, and patients with psychogenic non-epileptic seizures (PNES; n=10), compared to resting controls (n=10). Metrics of EEG time-series data were evaluated as biomarkers of the perturbation response including variance, autocorrelation, and phase-based synchrony measures. We observed considerable differences in all group biomarker distributions during stimulation compared to controls. In particular, variance and autocorrelation demonstrated greater changes in epochs close to PPR transitions compared to earlier stimulation epochs. Comparison of PPR and spontaneous seizure morphology found them indistinguishable, suggesting PPR is a valid proxy for seizure dynamics. Also, as expected, posterior channels demonstrated the greatest change in synchrony measures, possibly reflecting underlying PPR pathophysiology mechanisms. We clearly demonstrate observable changes at a group level in cortical excitability in epilepsy patients as a response to perturbation in EEG data. Our work re-frames photic stimulation as a non-invasive perturbation paradigm capable of inducing measurable changes to brain dynamics. Copy rights belong to original authors.

S., Demirtas, M., Falcon, C., Gispert, D., Bosch, B., Balasa, M., Kringelbach, M. L., Sanchez, R., Ruffini, G., Deco, G. Abstract: One of the potential and promising adjuvant therapies for Alzheimer's disease is that of non-invasive transcranial neurostimulation to potentiate cognitive training interventions. Conceptually, this is achieved by driving brain dynamics towards an optimal state for an effective facilitation of cognitive training interventions. However, current neurostimulation protocols rely on experimental trial-and-error approaches that result in variability of symptom improvements and suboptimal progress. Here, we leveraged whole-brain computational modelling by assessing the regional susceptibility towards optimal brain dynamics from Alzheimer's disease. In practice, we followed the three-part concept of Dynamic Sensitivity Analysis by first understanding empirical differences between healthy controls and patients with mild cognitive impairment and mild dementia due to Alzheimer's Disease; secondly, by building computational models for all individuals in the mild cognitive impairment and mild dementia cohorts; and thirdly, by perturbing brain regions and assessing the impact on the recovery of brain dynamics to the healthy state (here defined in functional terms, summarised by a measure of metastability for the healthy group). By doing so, we show the importance of key regions, along the anterior-posterior medial line, in driving in-silico improvement of mild dementia and mild cognitive impairment groups. Moreover, this subset consists mainly of regions with high structural nodal degree. Overall, this in-silico perturbational approach could inform the design of stimulation strategies for re-establishing healthy brain dynamics, putatively facilitating effective cognitive interventions targeting the cognitive decline in Alzheimer's disease.

Abstract: Neurofunctional dysregulations in spatially discrete areas or isolated pathways have been suggested as neural markers for attention deficit hyperactivity disorder (ADHD). However, multiscale perspectives into the neurobiological underpins of ADHD spanning multiple biological systems remain sparse. This points to the need of multi-levels of analysis encompassing brain functional organization and its correlation with molecular and cell-specific transcriptional signatures are stressed. Here, we capitalized on diffusion mapping embedding model to derive the functional connectome gradient, and deployed multivariate partial least square (PLS) method to uncover the enrichment of neurotransmitomic, cellular and chromosomal connectome-transcriptional signatures of ADHD. Compared to typical control, ADHD children presented connectopic cortical perturbations in lateral orbito-frontal and superior temporal regions, which had also been validated in another independent sample. This gradient-derived variants in ADHD further aligned spatially with distributions of GABAA/BZ and 5-HT2A receptors and co-varied with genetic transcriptional expression. Cognitive decoding and gene-expression annotation showed the correlates of these variants in memory, emotional regulation and spatial attention. Moreover, the gradient-derived transcriptional signatures of ADHD exhibited enriched expression of oligodendrocyte precursors and endothelial cells, and were mainly involved as variants of chromosome 18, 19 and X. In conclusion, our findings bridged in-vivo neuroimging assessed functional brain organization patterns to a multi-level molecular pathway in ADHD, possibly shedding light on the interrelation of biological systems that may coalesce to the emergence of this disorder.

However, we find that two established mitophagy receptors, BNIP3 and BNIP3L/NIX, violate this assumption. Rather, BNIP3 and NIX are constitutively delivered to lysosomes in an autophagy-independent manner. This alternative lysosomal delivery of BNIP3 accounts for nearly all of its lysosome-mediated degradation, even upon mitophagy induction. To identify how BNIP3, a tail-anchored protein in the outer mitochondrial membrane, is delivered to lysosomes, we performed a genome-wide CRISPR screen for factors influencing BNIP3 flux. By this approach, we revealed both known modifiers of BNIP3 stability as well as a pronounced reliance on endolysosomal components, including the ER membrane protein complex (EMC). Importantly, the endolysosomal system regulates BNIP3 alongside, but independent of, the ubiquitin-proteosome system (UPS). Perturbation of either mechanism is sufficient to modulate BNIP3-associated mitophagy and affect underlying cellular physiology. In short, while BNIP3 can be cleared by parallel and partially compensatory quality control pathways, non-autophagic lysosomal degradation of BNIP3 is a strong post-translational modifier of BNIP3 function. More broadly, these data reveal an unanticipated connection between mitophagy and TA protein quality control, wherein the endolysosomal system provides a critical axis for regulating cellular metabolism. Moreover, these findings extend recent models for tail-anchored protein quality control and install endosomal trafficking and lysosomal degradation in the canon of pathways that ensure tight regulation of endogenous TA protein localization.

Abstract: We investigated if learned associations between visual and auditory stimuli can afford full cross-modal access to working memory. Previous research using the impulse perturbation technique has shown that cross-modal access to working memory is one-sided; visual impulses reveal both auditory and visual memoranda, but auditory impulses do not seem to reveal visual memoranda (Wolff et al., 2020b). Our participants first learned to associate six auditory pure tones with six visual orientation gratings. Next, a delayed match-to-sample task for the orientations was completed, while EEG was recorded. Orientation memories were recalled either via their learned auditory counterpart, or were visually presented. We then decoded the orientation memories from the EEG responses to both auditory and visual impulses presented during the memory delay. Working memory content could always be decoded from visual impulses. Importantly, through recall of the learned associations, the auditory impulse also evoked a decodable response from the visual WM network, providing evidence for full cross-modal access. We also observed that after a brief initial dynamic period, the representational codes of the memory items generalized across time, as well as between perceptual maintenance and long-term recall conditions. Our results thus demonstrate that accessing learned associations in long-term memory provides a cross-modal pathway to working memory that seems to be based on a common coding scheme.

W., Slager, N., McKenzie, S., Yoon, E., Diba, K. Abstract: Optogenetics are a powerful tool for testing how a neural circuit influences neural activity, cognition, and behavior. Accordingly, the number of studies employing optogenetic perturbation has grown exponentially over the last decade. However, recent studies have highlighted that the impact of optogenetic stimulation/silencing can vary depending on the construct used, the local microcircuit connectivity, extent/power of illumination, and neuron types perturbed. Despite these caveats, the majority of studies employ optogenetics without simultaneously recording neural activity in the circuit that is being perturbed. This dearth of simultaneously recorded neural data is due in part to technical difficulties in combining optogenetics and extracellular electrophysiology. The recent introduction of LED silicon probes, which feature independently controllable miniature LEDs embedded at several levels of each of multiple shanks of silicon probes, provides a tractable method for temporally and spatially precise interrogation of neural circuits. Here, we provide a protocol addressing how to perform chronic recordings using micro LED probes. This protocol provides a schematic for performing causal and reproducible interrogations of neural circuits and addresses all phases of the recording process: introduction of optogenetic construct, implantation of the micro LED probe, performing simultaneous optogenetics and electrophysiology in vivo, and post-processing of recorded data.

M., Maidorn, M., Martinez-Carranza, M., Hosseini, H., Saal, K. A., Oleksiievets, N., Prigge, M., Tsukanov, R., Stenmark, P., Fornasiero, E. F., Opazo, F. Abstract: Imaging of living synapses has relied for over two decades on the overexpression of synaptic proteins fused to fluorescent reporters. This strategy changes the stoichiometry of synaptic components and ultimately affects synapse physiology. To overcome these limitations, here we introduce a nanobody that binds the calcium sensor synaptotagmin-1 (NbSyt1). This nanobody functions in living neurons as an intrabody (iNbSyt1) and is minimally invasive, leaving synaptic transmission almost unaffected, as demonstrated by the crystal structure of the NbSyt1 bound to synaptotagmin-1 and by our physiological data. Its single-domain nature enables the generation of protein-based fluorescent reporters, as we showcase here by measuring spatially-localized presynaptic Ca2+ with an NbSyt1- jGCaMP8 chimera. Moreover, its small size makes the NbSyt1 ideal for various super-resolution imaging methods. Overall, NbSyt1 is a versatile binder that will enable imaging in cellular and molecular neuroscience at a higher precision than possible in the past, over multiple spatiotemporal scales.
