Abstract

Animals were rewarded for increasing (uptrain) or decreasing (downtrain) the amplitude of a 30 ms surface positive component of a somatosensory evoked potential (SEP) evoked by innocuous stimulation of the spinal trigeminal tract. The reflex movement produced by the evoking stimulus had a larger amplitude in uptraining than downtraining. This change in reflex amplitude suggests that operantly conditioning SEP amplitude was correlated with a change in innocuous somatosensory activity. There was no change in continuous non-timelocked movement associated with conditioning. This latter finding suggests that SEP conditioning is not necessarily mediated by such movement.
