| Abstract: | Extracellular recording techniques were used on cats anesthetized with Nembutal to illustrate antidromic activation of pontine neurons produced by stimulating the medial and occasionally the superior cerebellar peduncle, the cerebellar central nuclei, pyramidal tract, and sensorimotor region of the cortex. Of the pontine nucleus projection, that extending to the lateral cerebellar nucleus was the most clearly defined. Stimulation of the pyramidal tract, central cerebellar nuclei and the superior cerebellar peduncle was found to produce monosynaptic excitation of pontine neurons. The significance and special features of the connections identified are discussed in connection with cortico-pontocerebellar system function.L. A.
