Abstract
5 rhesus and 2 cebus monkeys were operated for removal of the anterior cingular gyrus (area 24), and subsequently observed for 2-14 wks. There was restlessness and hyperactivity, with increase of tameness,but the changes diminished after a few wks. No pure area 24 lesion was created but, through efferent fibers, connections with areas 6, 8, 9, 10, 29 and the anterior border of area 4 could be demonstrated. Most of the injured areas sent fibers to the cingular cortex and, from the posterior part, into the anterior nucleus of the thalamus.Keywords
