A COMMENT ON HIPPOCAMPUS AND BEHAVIOR

R. J. DOUGLAS (SEE 41:8) RECENTLY REVIEWED THE LITERATURE ON THE BEHAVIORAL EFFECTS OF LESIONS OF THE HIPPOCAMPUS AND CONCLUDED THAT THE LESION PRODUCES A UNITARY DEFICIT. DOUGLAS CONSIDERED SOME OF THE DATA WHICH CONTRADICT HIS CONCLUSION AND STATED THAT MANY OF THE CONTRADICTIONS ARE DUE TO THE USE OF SMALL LESIONS. THE HYPOTHESIS IS ADVANCED THAT SMALLER LESIONS ARE ALSO APPROPRIATE SINCE THERE IS CONSIDERABLE EVIDENCE THAT THE HIPPOCAMPUS IS NOT EQUIPOTENTIAL IN ITS CONTRIBUTION TO BEHAVIOR. A REVIEW OF THIS EVIDENCE IS PRESENTED. (16 REF.) (PsycINFO Database Record (c) 2006 APA, all rights reserved). © 1968 American Psychological Association.
