SUMMARY:Multiple Rhythms and Switches in the Nervous System
DESCRIPTION:Featuring Nancy Kopell\, Boston University\nHosted by: Raj Moha
	nty\n\nPart of the Physics Department Colloquia Series.\n\nNetworks of neur
	ons in the nervous system can produce a variety of temporal patterns of dif
	ferent frequency; the same network can produce different rhythms at differe
	nt times\, or several rhythms at one time. We focus here on the gamma (30-9
	0 Hz) and theta (4-12 Hz) rhythms produced in the hippocampus\, a part of t
	he nervous system critical for learning and recall. We discuss experiments 
	and models that suggest that there are separate subnetworks that produce th
	e different rhythms; the sharing of components of the networks induces comp
	etition between the rhythms\, which can lead to suppression of one of the r
	hythms\, or nesting of the rhythms. We show how low-dimensional maps can he
	lp to understand the properties of the cells and networks to allow this to 
	happen.
