## Article: We Got Rhythm: Dynamical Systems of the Nervious System

Notices of the American Mathematical Society 47(1), January 2000, pages 6-16, contains an article by Nancy Kopell. This article, based on the 1999 Josiah Willard Gibbs lecture, discusses mathematical models for the rhythms that are observed in certain kinds of brain activity, as well as transitions between different rhythms. This article is avaiable as a pdf file at: http://www.ams.org/notices/200001/fea-kopell.pdf.
