1. Post-natal development of the retinal and cerebellar projections onto the medial bank of the lateral suprasylvian visual area was examined by using the field potential method and, additionally, by the orthograde horseradish peroxidase method. 2. Optic nerve stimulation elicited a surface-positive, depth-negative field potential in the medial bank of the lateral suprasylvian area of adult cats. By contrast, in kittens younger than 3 weeks old, a surface-negative, depth-positive field potential was evoked. The response grew adult-like by 1 month of age. Corticocortical response, activated by stimulation of cortical areas 17 and 18, underwent a similar developmental change. 3. Cerebellar stimulation evoked a surface-negative, depth-positive wave from birth up to adulthood. Thalamocortical afferents from the ventroanterior and ventrolateral nuclei of the thalamus to the medial bank of the lateral suprasylvian area, which is presumed to be responsible for this cerebellar response, terminate mostly in layer I in both new-born kittens and adult cats. 4. The present results, and our previous morphological findings on the projections from the extrageniculate visual thalamus and visual cortical areas 17 and 18 onto the medial bank of the lateral suprasylvian area, were correlated with reference to the maturation of the neuronal circuit in the cortex.

UI	MeSH Term	Description	Entries
D009434	Neural Pathways	Neural tracts connecting one part of the nervous system with another.	Neural Interconnections,Interconnection, Neural,Interconnections, Neural,Neural Interconnection,Neural Pathway,Pathway, Neural,Pathways, Neural
D009900	Optic Nerve	The 2nd cranial nerve which conveys visual information from the RETINA to the brain. The nerve carries the axons of the RETINAL GANGLION CELLS which sort at the OPTIC CHIASM and continue via the OPTIC TRACTS to the brain. The largest projection is to the lateral geniculate nuclei; other targets include the SUPERIOR COLLICULI and the SUPRACHIASMATIC NUCLEI. Though known as the second cranial nerve, it is considered part of the CENTRAL NERVOUS SYSTEM.

D012160	Retina	The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.	Ora Serrata
D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.
