Killing of mice was suppressed in 18 out of 24 rats by electrical stimulation of the region ventral to the anterior septum lying between the vertical arm of the diagonal band of Broca and the rostral limb of the anterior commissure. The mean effective minimum stimulation intensity was 8.2 uA (60 HZ, RMS). Stimulation of the cingulate cortex did not suppress mouse killing (mean stimulus intensity: 38.7 uA). Electrical recordings revealed after discharge in response to the stimulation in only one animal. At the stimulation intensity which suppressed mouse killing, there was no significant suppression of eating in 6 of 9 animals tested. These results are consistent with other evidence implicating the region ventral to the anterior septum in the modulation of mouse killing in the rat.
