For the June edition of the Research Seminar Series, Dr. Jaime Tartar presents her research on sleep, brain function, and the gut-brain connection. She talks about how inconsistent sleep patterns and poor sleep quality can lead to physiological issues.
Dr. Tartar explores the science of sleep and its vital role in overall health and cognitive performance. She discusses the neurological impacts of sleep deprivation and chronic sleep restriction, as well as how these factors influence mood regulation at the brain level.
She also shares research findings on non-sleep deep rest and lucid dreaming, revealing that allowing people more time in bed can lead to longer sleep durations and reductions in hostility and somatic symptoms.

Jaime Tartar is a Professor of Neuroscience at Nova Southeastern University. She earned her Ph.D. in the Behavioral Neuroscience program at the University of Florida, where the focus of her research involved discovering long-term changes that occur in neurobiological pathways involved in stress responses and developing animal models of stress. Dr. Tartar has also completed Postdoctoral Training at Harvard Medical School, where she studied neurological consequences of sleep perturbations using in vitro electrophysiological recording techniques. She also received training in Sleep Medicine at Harvard Medical School. She was also awarded an Honorary Doctorate at Nova Southeastern University. Dr. Tartar is the co-founder and CEO of The Society for Sports Neuroscience—an academic organization for the field of Sports Neuroscience. Dr. Tartar's current research is focused on stress, sleep, and athletic performance in humans.
