| Abstract: | The properties of hypothalamic pathways activating sympathetic preganglionic neurons in the lateral horns of the spinal cord were studied in cats. This activation was shown to take place through reticulospinal sympathetic-activating neurons in the medulla. The possible zone of location of hypothalamic sympathetic-activating output neurons was shown by the scanning stimulation method to be in the posterolateral hypothalamus. Reticulospinal sympathetic-activating neurons in the medulla are probably excited monosynaptically by hypothalamo-sympathetic activating fibers projected on them.L. A.
