pubmed:abstractText
Neuronal responses in the pretectum (PT) were analyzed in 4-16 week old kittens after visual and electrical stimulation and compared with adult responses from a previous study. All three retinal fiber types projecting to the adult PT could be electrically activated in kittens from 4 weeks on. There was a dramatic reduction of response latencies to electric shocks to retinal afferents applied at the optic chiasm (OX) and optic tract (OT) in postsynaptic cells as a function of age, involving X-, Y-, and W-fibers. At four through six weeks postnatally the reduction in latency was found to be due to enhanced signal transmission at the axonal terminal region. Latency reduction continued after six weeks of life due to sharp increases in conduction velocity of the afferent fibers. Different steps in the maturation of visual response specifity were found for neurons of different functional types. Possible relationships are discussed between the development of neuronal responses of pretectal cells and the maturation of oculomotor behavior.
