In this episode, we unravel the findings of a fascinating study by Paula R. Haynes, Elana S. Pyfrom, Amita Sehgal, and their team, which shines a light on how our brains use sleep to recover and prepare for the next day. We simplify the complex science into easy-to-understand concepts, explaining why this process is crucial for our well-being and performance.

People have been reporting all kinds of strange sleep habits during the pandemic, and, according to sleep experts, it makes sense. Dr. Rebecca Spencer, a professor of brain sciences at the University of Massachusetts Amherst, and Dr. Amita Sehgal, a molecular biologist at the University of Pennsylvania, know that the sleep we get can be a reflection of the lives we lead. We dive into how the stresses and strains of these unpredictable times - not to mention greatly increased screen use - have disrupted our natural biological rhythms, and find out what it takes to get a good night’s rest.

In this podcast, Amita Sehgal, PhD, talks about using small-animal models, such as fruit fly models, to determine how and why we sleep. Do flies actually sleep? Listen in to find out! More at: www.consultant360.com/neurology.

Orla Smith, editor of Science Translational Medicine joins host Sarah Crespi to talk about what has changed in the past 10 years of microbiome research, what’s getting close to being useful in treatment, and how strong, exactly, the research is behind those probiotic yogurts. When you’re sick, sleeping is restorative—it helps your body recover from nasty infections. Meagan Cantwell speaks with Amita Sehgal, professor of neuroscience at the University of Pennsylvania and an investigator at Howard Hughes Medical Institute in Chevy Chase, Maryland, about the process of discovering a gene in fruit flies that links sleep and immune function.

What can we learn about human sleep from studying fruit flies? A lot more than you might think, as psychiatrist and researcher Matt Kayser explains this week. Matt and his colleagues are deepening our understanding of what drives the profound changes in sleep patterns across development—for example, newborns sleep all the time (except when their parents want them to), college students become nocturnal, and aging adults struggle to sleep soundly. His research promises to reveal the pathways in the brain that drive these shifts, and the effects of poor sleep on the developing brain. Matt and I discussed some of his recent research, as well as general principles in this area. Topics we covered included: The striking similarities in sleep across most species Why fruit flies are an especially good model for studying sleep Why we sleep, given the obvious downsides How and why sleep changes across development Why sleep deprivation early in life may have long-lasting effects The surprising advantages of spending less time in bed Implications of poor sleep on the aging brain The effects of mindfulness practice on insomnia If you're interested in the original research articles we discuss, you can find them through these links: A Sleep State in Drosophila Larvae Required for Neural Stem Cell Proliferation A Critical Period of Sleep for Development of Courtship Circuitry and Behavior in Drosophila The study on amyloid beta with implications for Alzheimer's Disease is still in the works. Dr. Matt Kayser completed his MD and PhD at the University of Pennsylvania where his research focused on the development of synapses (the connections that allow nerve cells to communicate with each other) in mammals. He continued at Penn for his psychiatric residency and in a research postdoc with Dr. Amita Sehgal using Drosophila (fruit flies) to examine how neural circuits give rise to complex behaviors—particularly sleep and brain function. He is currently an assistant professor of psychiatry in the Perelman School of Medicine at the University of Pennsylvania, and the creator and director of the Sleep Mental Health Clinic at Penn.

In this month's Cell Podcast, we learn about getting neural stem cells out of the lab and into the clinic, with Sally Temple (0:00), an important role for rare copy number variations in autism, with Matthew State and Michael Wigler (8:30), the dangers of midnight feasts for fruit fly fertility, with Amita Sehgal (18:04), and fitness costs and crosstalk in the evolution of host defense pathways, with Ruslan Medzhitov (24:32).

Three talks featuring University of Pennsylvania experts (Drs. Wade Berrettini, John Hogenesch, and Amita Sehgal) on genomics and different aspects of behavior, including biological rhythms, sleep, addiction, eating, stress and depression. Moderated by Science Columnist from the Philadelphia Inquirer, Faye Flam.

Panel of University of Pennsylvania professors (Drs. Wade Berrettini, John Hogenesch, Amita Sehgal, Kendra Bence and Irwin Lucki) take on audience questions about genomics and different aspects of behavior, including biological rhythms, sleep, addiction, eating, stress and depression. Moderated by Science Columnist from the Philadelphia Inquirer, Faye Flam. This is part two of an evening that started with three talks by Drs. Berrettini, Hogenesch and Sehgal.
