Running Recognition of Configural Stimuli by Fornix-Transected Monkeys

Abstract

Six Rhesus monkeys were trained in a running recognition task with visual-spatial configurations as the stimuli to be remembered. Following pre-operative training half the monkeys were subjected to fornix transection and half to a control operation. Fornix transection produced a severe and apparently permanent impairment. These results add to the evidence that fornix transection produces defects in memory which cannot be explained as secondary consequences of impairments of perception.
