FEAR AND PAIN: THEIR EFFECT ON SELF-INJECTION OF AMOBARBITAL SODIUM BY RATS.
Rats receiving occasional brief electric shocks pressed a bar, which caused them to be injected with amobarbital sodium, more frequently than the control rats to which they were yoked and which were injected when their partners pressed but whose own bar activated only a recorder. This differential effect was not shown by pairs run without shocks.
