I will continue our work on lesion-induced synaptogenesis in the hippocampus of the adult rat. Electron micrcoscopic analysis will be carried out to determine the number of synapses contributed by the residual afferents which sprout and replace those lost. Correlative electrophysiological experiments are planned to eucidate the functional characteristics of the new circuitry. In addition, we will continue our experiments on axon regeneration in the adult CNS. BIBLIOGRAPHIC REFERENCES: Goldowitz, D., White, W., Steward, O., Cotman, C., and Lynch, G.
