An intracerebral cannula system was surgically implanted in each of 21 rats. The responses of each S were observed following the temporary deposition of acetylcholine chloride, sodium pentothal, 1-epinephrine, or the placement of a blank cannula. Acetylcholine produced drinking in the hypothalamus and stereotyped standing postures in the reticular system Ss. Sodium pentothal produced an increment in feeding responses in the ventrolateral-reticular-system Ss and an increment in grooming in the dorsomedial-reticular-system Ss.
