PSYC 427 Lecture Notes - Lecture 16: Superior Cerebellar Peduncle, Cerebellar Peduncle, Pontine Nuclei
Document Summary
Cerebellum comprises an outer cover of gray matter (cerebellar cortex) and 3 pairs of deep nuclei (fastigial, anterior and posterior interpositus, and dentate). Two longitudional furrows, that are most prominent ventrally, define an elevated midline ridge (vermis). Their cerebellum is similar to ours. all mammals have cerebellums. It is intriguing because structure of cerebellum is very uniform; this structure has one kind of computational machinery which applies same logic to all kinds of inputs/outputs cerebellum connects to spinal cord, basal ganglia, throughout cerebellar cortex. Outputs from cerebellar cortex (purkinje neurons)) are inhibitory. Deep within cerebellum, can see symmetric structure about midline. Dentate (lateral), inner posidous (intermediate), and most medial is called fastigial. All output is channeled through deep cerebellar nuclei. Inputs and outputs that go to cerebellar cortex come in and out through cerebellar peduncles. Saggital plane can see structure of cerebellum. There are many lobules (numbered from 1 10).
