SELF-STIMULATION - FAILURE OF PRETRIAL STIMULATION TO AFFECT RATS ELECTRODE PREFERENCE

6 male Sprague-Dawley rats and 5 white male rats running an alley for brain-stimulation reward (BSR) ran as fast when primed with another electrode as when primed with the electrode used for reward. In a T maze, priming on 1 electrode did not induce Ss to choose that electrode in preference to the other. The drive-like aftereffect of BSR was not selectively directed toward the rewarding electrode used to create the aftereffect. (19 ref.)
