Abstract:

The Center for the Study of Rhythmic Processes continued its work on Central Pattern Generators CGPs, notably on the vertebrate spinal CPG for undulatory locomotion, and the invertebrate crustacean stomatogastric ganglion STG. For the lamprey, a primitive vertebrate, experiments were designed and performed involving transduction of mechanical motion to neural activity these experiments were combines with mathematical theory to help understand the relation of structure to function in that network. Other topics investigated included the effects of long coupling fibers, the relationship between muscle activation and movement, and the ability of the network to regenerate. Work on the STG included results on neuromodulators that change the output of the network and mathematical modelling of individual cells as well emergent properties of the network.
