Abstract
Brain stimulation classified behaviorally as rewarding or aversive was observed to have different effects on photic cortical evoked potentials in rats. Following a rewarding brain stimulation the early cortical response is attenuated and remains so for at least 25-30 sec; its recovery function is flat to 25-30 sec. Following an aversive stimulation, the response is severely attenuated for 5-6 sec but then recovers and overshoots control levels 15 sec following brain stimulation and thereafter.
