| Abstract: | Descending projections from the cortex and basal ganglia to the hypothalamic locomotor region were studied in cats by the retrograde axonal transport of horse-radish peroxidase method. Neurons forming direct projections to the physiologically identified hypothalamic locomotor region are diffusely scattered over different gyri, but predominantly in areas 4 and 6 of the motor cortex, and also in the entopeduncular nucleus. Powerful cortico- and pallido-hypothalamic projections mainly do not reach as far as the most caudal zones of the hypothalamus, where the region whose electrical stimulation evokes locomotion lies.A.
