title: [Neurophysiologic analysis of the development of cortico-striatal connections during postnatal ontogeny in the rabbit].
abstract: Responses of the caudate nucleus to electrical stimulation of the ipsilateral motor cortex were recorded in 2-30 day old and adult rabbits. The caudate response could be evoked already in the youngest (3 day old) animals. The configuration and topography of these evoked potentials were identical to the responses in adult rabbits. The latency was about 10 ms in the youngest rabbits. A significant decrease of the latency occurred between the 16-17th and 20th day. The definite values of amplitude and latency were reached to the 30th day. The results suggest an early maturation of the corticostriatal input in rabbit and correlate with its early structural maturation.
