Podcasts about light intensity

Nik from Rooted Leaf Nutrients (use code GROWCAST) returns for another deep dive- this time moving away from soil fertilizer elements and delving into watering dynamics. Nik introduces us a concept called SPAC, or soil, plant, air, continuum (AKA the soil, plant, atmosphere continuum). This concept encompasses a more holistic view when it comes to optimal climate conditions in our cannabis grows- whereas singular metrics like VPD can sometimes be only part of the picture. Nik discusses how we should be thinking about what happens to all that water that we dump into the soil system after we put it in there... Plants, after all, are just water lifting mechanisms designed to move that water from the soil into the atmosphere. Understanding and mastering this cycle leads to a healthier, and more vigorous garden.

BIO:Chroma was created when the founder was looking at natural solutions to speed healing after a climbing accident.  When there were no other high power density devices on the market, the Ironforge was born, quickly followed by a handful of other light devices designed to make a big impact with only a small lifestyle adjustment.Meet The Founder...Chroma began when Michael Chapiro, a NASA, NSF, Air Force, and MDA funded engineer, injured himself rock climbing...While searching for a solution to help heal a partially torn A2 pulley in his finger, Michael discovered a clear market gap. All existing red & near infrared (NIR) products were simply stock greenhouse panels with the LED's swapped out. Before the prototype of the Ironforge, there was nothing built for targeted high power density light treatment. SHOWNOTES:

Workout 71: (Medium Interval Workout) The more we practice the easier it becomes to provide ourselves with more specific targets inside our workouts. When the performance monitor is set to display your previous effort, there is a confidence that is owned and a motivation that drives us from within. When put together, there is progress.   Warm Up (~10 Minutes) (Programming begins at 3:45) Arms Only Rowing Arms and Body Rowing Arms, Body, Unlock Legs Rowing Arms, Body, Unlock and Compress Legs Bring Up Stroke Rate Bring Up Power   Workout (~20 Minutes) (Programming Begins 21:00) 3 Intervals of 6 Minutes with 3 Minutes of Rest   The 6 Minutes are broken down into: 2 Minutes @22 with a Light Intensity (light/HR Zone 2/RPE 4/2k+) into 3 Minutes @24 with a Moderate Intensity (medium/HR Zone 3/RPE 6/2k) into 1 Minute @28 with a Hard Intensity (high/HR Zone 4/RPE 8/2k-)   Interval 1 is a test Row where we set ourselves a base. We use the ReRow function and the Pace Boat screen on the Performance Monitor to help motivate our effort in Interval 2 and Interval 3   Cool Down: Take things easy for the last few minutes on or off of your machine   Want to Learn or Practice the Basics of Rowing on the Concept2 RowErg?  As The Flywheel Spins "Row Basics"   Remember, feedback is important!  Please forward any questions or comments you may have to info@concept2.com (use "Podcast" in the subject line of your email).   Please read the following before participating.

Abstract: Background: The beneficial effects of both single-session bouts of aerobic exercise and therapeutic exercise interventions on the cortical regions associated with executive functions (i.e., prefrontal cortex (PFC)) have been well documented. However, it remains unclear whether aerobic exercise can be used to offset temporary fluctuations in cortical activity. Objective: The current study sought to determine whether a single session of moderate intensity aerobic exercise can offset the attenuating effects of continuous theta burst stimulation (cTBS) targeting the dorsolateral prefrontal cortex (dlPFC). Methods: Twenty-two right-handed participants between 18-30 years completed a 20 minute session of light intensity (10% heart rate reserve (HRR)) and moderate intensity (50% HRR) exercise in a counterbalanced order. Following each exercise session, participants received active cTBS to the left dlPFC. Changes in executive functions were quantified using a flanker paradigm employed at baseline, post-exercise and post-cTBS time points. Additionally, EEG methodologies were used to measure changes in inhibitory control specific event-related potential components (i.e., P3 and N2) in response to the flanker task. Results: Behavioural results from the flanker task revealed a significant improvement in task performance following an acute bout of moderate intensity exercise. Furthermore, the effect of cTBS in both light and moderate intensity conditions were non significant. Similarly, EEG data from P3 and N2 ERP components revealed no changes to amplitude across time and condition. P3 latency data revealed a significant effect of time in the light intensity condition, such that latency was faster following cTBS. Similarly, latency data within the N2 ERP component revealed a significant effect of time on congruent trials in the light intensity condition; N2 latency was faster following cTBS. Conclusion: The current study revealed that light and moderate intensity exercise may provide a buffer to cTBS- induced attenuation of the dlPFC. This study provides empirical and theoretical implications on the potential for exercise to promote cognitive control. Copy rights belong to original authors. Visit the link for more info

Editor in Chief Fred Rivara and Deputy Editor Steve Fihn discuss research published in JAMA Network Open in April 2019. Article available here.

To comprehend how the brain performs efficient computation, it is important to understand the way sensory information is represented in the nervous system. Under natural conditions, sensory signals have to be processed with sufficient accuracy under functional and resources constraints. Here I use motion vision in the fly Calliphora vicina to study the influence of two behaviorally relevant environmental properties - temperature and light intensity - on the representation of motion information in the responses of the neuron H1. The goal was to quantify how these environmental properties affect the response variability, information content, coding efficiency and temporal scale. I show that the firing precision is determined largely by the light intensity rather than by temperature. Moreover, a better firing precision barely improves the information rate, which closely follows the mean firing rate. Altogether, my results suggest that the robustness of the motion information processing against temperature variations depends on the quality of the input signal. Furthermore, flies seem to use the input signal-to-noise ratio to improve the information rate and reduce the time-scale of the response simultaneously, by increasing the mean firing rate, rather than the firing precision.
