Neuronal Dynamics - Part I of II

1:00 PM-3:00 PM
Koali (Salon 5)

For Part II, see MS21.

Oscillations 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. Examples of network activity include synchronous behavior in which all the cells oscillate in phase, localized bumps of asynchronous rhythms, and propagating waves of activity. The speakers in this minisymposium will discuss complex activity patterns arising from an important neuronal system. The goal is to stimulate cross-disciplinary interactions between experimentalists, computational neuroscientists and mathematicians.
