Physics Colloquium, November 26, 2002Neuronal DynamicsDavid TermanOhio State University, Dept. of MathematicsOscillations and other patterns of neuronal activity arise throughout the central nervous system. This activity has been observed in sensory processing, motor activities, and learning, and has been implicated in the generation of sleep rhythms, epilepsy, and parkinsonian tremor. Mathematical models for neuronal activity often display an incredibly rich structure of dynamic behavior. In this lecture, I describe how the neuronal systems can be modeled, various types of activity patterns that arise in these models, and mechanisms for how the activity patterns are generated. In particular, I present a recent model for neuronal activity patterns in the basal ganglia, a part of the brain involved in movement disorders. 3.30 p.m., Smith Laboratory, Room 1005Refreshments served in Smith 1094 at 3:00 p.m. |
