In 1954 Perl accepted a faculty position at the State University of New York, College of Medicine, Syracuse ( now known as SUNY Upstate Medical University ), where he not only researched crossed spinal reflexes, but also renewed his interest in the activity of C-fiber afferent fibers and their projections to the spinal cord.

Based on these observations, he developed the concepts of " motor set " and " transcortical reflex " . " Psychomotor set " describes neural activity that occurs when a motor action in response to a stimulus ( " go-cue " ) is being prepared . " Transcortical reflex " describes the operation of motor cortex in the way similar to spinal reflexes that influence spinal motoneuron firing.
