S ummary 1. Two ascending pathways are described which influence responses evoked in the hypothalamic ventromedial nucleus by septal and amygdaloid stimulation. 2. 100/second medial mesencephalic tegmental stimulation and caudal diencepha‐lic periventricular stimulation leads to enhancement of the septal‐ventromedial and suppression of the amygdaloid‐ventromedial response. 3. 100/second stimulation of a region involving the magnocellular medial geniculate nucleus and centrum medianum‐parafascicular nucleus complex results in a suppression of both septal and amygdaloid‐ventromedial evoked responses. 4. Lesions along the course of the periventricular region of the hypothalamus abolish the effect of midbrain stimulation upon ventromedial nucleus responses. Lesions of the magnocellular medial geniculate or centrum medianum do not alter the midbrain‐hypothalamic influence.
