The effects were observed on spinal scratch generator activity of the afferent inflow produced in decerebrate immobilized cat by regular passive movement of the hindlimb paw following a trajectory close to that observed during actual scratching. These consisted of substantial alteration in scratch generator efferent activity, which thereby became phase-locked with the afferent flow. Synchronization between efferent scratching activity and passive limb motion has occurred by the first movement cycle and phase-locking was the reverse of that seen during actual scratching.
