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.
