The behavioral effects of radical bilateral hippocampectomies and partial neodecortization are described in a number of behavioral situations. Both postoperative retention and postoperative acquisition paradigms were used in different studies. The studies show that the ability of a hippocampectomized rat to withhold responses is not completely absent, but depends, in part, upon the nature of previous training. Furthermore, we have found that preoperative acquisition of a response requiring a withholding of a response does not prevent the postoperative loss of the ability to perform the response following hippocampal destruction. Other studies of postoperative retention of simple behavioral responses following damage to the limbic system, diencephalon, and basal ganglia are included. Author
