Evoked Potentials: Modifications by Classical Conditioning

H. Begleiter 1 and A. Platz 1

1 Department of Psychiatry, Downstate Medical Center, Brooklyn, New York

Visual evoked potentials to a positive discriminative stimulus change systematically during sensory conditioning and extinction. Changes due to conditioning are manifested in the increased amplitude of the late component of the evoked response. This effect is attenuated during extinction and reappears after reconditioning.
