ABSTRACT
This book is based on the very interesting idea that preoperative experience may protect brain-damaged animals against deficits that would normally occur after brain lesions and that the same may be true for brain-injured humans. In some ways, it is the opposite side of the coin from recovery of function after brain injury, since the preoperative experience eliminates, reduces, or gets around the deficits before they occur rather than after they occur. In this light, much is to be gained by analyzing the various kinds of preoperative protective effects along the same lines as we classically have analyzed postoperative recovery effects.
