SEPTAL AND HYPOTHALAMIC STIMULATION OF UNANESTHETIZED CATS

Abstract

In six cats bipolar stainless steel electrodes were stereotactically implanted in septal and hypothalamic loci. Observations were made of autonomic, somatomotor and behavioral responses to electrical stimulation delivered while the cats were unanesthetized and unrestrained. Septal stimulation evoked sympathetic and parasympathe tic responses in varying combinations on various days. This suggested that responses to septal stimulation were influenced by the relative ex citability of anterior and posterior hypotha lamic neurons at a given time. Shivering was produced during stimulation of both septal and hypothalamic loci, thereby confirming previous results obtained from anesthetized preparations.
