Active and passive avoidance learning in controls and schizophrenic patients on racemic propranolol and neuroleptics
J Gruzelier, S Thornton, D Staniforth, S Zaki and N Yorkston
Normal controls and schizophrenic patients on propranolol as sole drug or
combined with neuroleptics showed superior active and passive avoidance
learning to schizophrenic patients who were medicated with conventional
neuroleptics only. Active avoidance involved responding quickly, passive
avoidance withholding a response to avoid an unpleasant noise and reacting
to the appropriate stimulus. This may reflect an improvement brought about
by propranolol in the limbic regulation of stimulus and response processes.
