IDDRC Seminar Series Workshop Announcement Tuesday, December 2nd 2014 at 1:30pm Kennedy Center, Room 901 Cortical Rhythms Facilitate Bottom-Up and Top-Down Processing Nancy Kopell, Ph.D. Boston University Abstract: The brain produces electrical activity in all states and all times, with ever-changing spectral properties. Though we are beginning to learn the mechanisms of the multiple and complex "brain rhythms", it is still a mystery how such rhythms participate in cognition. In this talk, I argue that the physiological bases of brain rhythms (not just their frequencies) are important for cognitive function, and illustrate this with examples concerning bottom-up and top-down processing. I also argue that modeling will be critical in understanding how physiology is tied to function. Biographical Note: Dr. Nancy Kopell is a William Fairfield Warren Distinguished Professor in the Department of Mathematics and Statistics at Boston University. She is a member of the National Academy of Sciences and the American Academy of Arts and Sciences, and was named an Honorary Member of the London Mathematical Society (one or two awarded worldwide each year). She has held fellowships from the Alfred P. Sloan Foundation, the J.S. Guggenheim Foundation and the John D. and Catherine T. MacArthur Foundation. Prof. Kopell is interested in dynamics of nervous system, including the mechanistic origins of brain rhythms, their use in cognition, and their role in cognitive disorders. She started and continues to run an NSF supported "Discovery Network" called the Cognitive Rhythms Collaborative, a group of more than two dozen labs (mostly) in the Boston area, whose mission to facilitate collaboration among theorists and experimentalists on problems involving brain dynamics.
