Conditioned reflex switching over in unrestrained dogs

Conditioned switching-over was studied in unrestrained animals by means of instrumental alimentary conditioned reflexes of pressing the pedal. A complex of auditory and spatial factors (start-ground) served as conditioned alimentary signal. Backward connections were stable and were manifested in the teturning of the animal to the start-ground after feeding. It has been confirmed that the observed working readiness is a conditioned reflex of a tonic type.
