I don't have my notes with me (of course!), but what I recall from Delgado's
experiment was that he stimulated the caudate
nucleus, which is involved in motor control. When he remotely stimulated this brain
region, the bull stopped charging and began
circling. If I remember correctly, Pinel has a great description of Delgado's
experiment in his Biopsychology text.
