Response
Feedback:
The only statement here that is true of the PAG is that electrical stimulation of the
PAG can reduce or stop chronic pain. This electrical stimulation is so powerful that
abdominal surgery can be performed without drugs in animals that are receiving
such stimulation. The PAG is located in the midbrain. If morphine and other opiate
drugs exert their well-known analgesic effects partly through direct action in the
PAG it can reduce pain. Alcohol, on the other hand, will not reduce pain. The correct
answer is “electrical stimulation of the PAG can reduce or stop chronic pain.”
