Striatal connections and influences on somatosensory and photic projections to the hypothalamus

摘要: Abstract Electrophysiological connections between the hypothalamus and corpus striatum effects of latter on afferent projections to were studied in cats. Short-latency projections, which resistant pentobarbital anesthesia anoxia, able follow high frequency stimulation showed post-tetanic potentiation, demonstrated these two structures. Single conditioning stimuli caudate nucleus globus pallidus had variable inhibitory somatosensory visual hypothalamus. However, bilateral chronic lesions head produced a considerable shortening recovery cycle short-latency potentials postero-lateral but did not affect long-latency responses propagating polysynaptic systems anterior Such have, contrary, prolonged photic response pre-optic area. These results indicate that apparently has phasic facilitatory influences hypothalamic respectively.
