Seminar: Living In The Cold – Hibernation And Retinal Neurobiology

Wei Li, Chief and Senior Investigator at the National Eye Institute/National Institutes of Health, Retinal Neurophysiology Section will be delivering a seminar on “Living In The Cold – Hibernation And Retinal Neurobiology” on Wednesday, December 18th at 12:00 Noon in the  Moran Eye Center auditorium.

Abstract: We are interested in understanding how the retina adapts to extreme metabolic conditions, such as those experienced by hibernating animals.  We believe that metabolism is one of the core issues pertaining to the health and pathological change in the retina.  By studying hibernating animals (the ground squirrel), we hope to identify strategies that can help the retina better cope with metabolic stresses that feature in retinal disease.  In this presentation, I will discuss several adaptive features of the ground squirrel retina during hibernation.

Samer Hattar, Chief and Senior Investigator at the National Institutes of Mental Health/National Institutes of Health will be delivering a seminar on “Retinal and Brain Circuits Underlying the Effects of Light on Behavior” on Wednesday, September 6th at 12:00 Noon in the  Moran Eye Center auditorium.

Abstract: In this presentation, I will talk about how environmental light through photoreceptors in the retina reaches the brain to influence our internal ,timing, sleep, mood and learning. I will provide detailed retinal circuits, and new brain regions that are responsible for the effects of light on each aforementioned function. In the process, my presentation would be applicable to our modern lifestyle where we extended the day into the night by using artificial lighting and electronic devices that are delaying our sleep onset and leading to sleep disruption and debt. These changes could have major societal impacts that I am going to discuss.
