In six cats bipolar stainless steel electrodes were stereotactically implanted in septai 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 parasympathetic responses in varying combinations on various days. This suggested that responses to septal stimulation were influenced by the relative excitability of anterior and posterior hypothalamic neurons at a given time. Shivering was produced during stimulation of both septal and hypothalamic loci, thereby confirming previous results obtained from anesthetized preparations.
