Abstract : The Center for the Study of Rhythmic Processes began operation in the academic year 1986-87. It brought together mathematicians and biologists to work on problems of mutual interest. During the first year, the Center focused on two sets of problems. The first involved the structure and function of the intersegmental coordinating system of the vertebrate spinal cord, for which the lamprey provides an excellent model system. A broadly applicable mathematical framework was constructed for analyzing this system, and new mathematical techniques were invented. A new technology was put into use which has the potential of providing information not previously obtainable . Many of the major researchers working on this preparation were consolidated under the auspices of the center, and many new collaborations were formed. The other involved small neural networks, such as the stomatogastric ganglion of the lobster. Detailed mechanisms of function and control were investigated, and mathematical tools were applied to investigate how the circuits change under modulation. Keywords: Oscillators; Regeneration; Central pattern generators; Mathematical modeling; Sensory feedback; Neural networks; Neuromodulators.
