Drug studies have long been a magnet for behavioral biologists. The biochemical changes drugs produce in brain, the neurophysiological effects they bring about, their alterations of unconditioned and conditioned behavior, their interactions with stimuli-including drug stimuli-that produce all manner of central effects: all these subjects have been of utmost importance.
