What is Gating of tactile input from the hand: II. Effects of remote movements and anaesthesia about?

Tactile sensations of flutter or pressure were evoked in alert human subjects by intraneural microstimulation in the median nerve. Ratings were obtained of the magnitude of sensations at threshold for conscious detection during movement of the finger to which they were projected, of neighbouring fingers or of the opposite hand. Results showed that inhibition of flutter sensation was maximal in the moved finger (48%), with a weaker graded effect from adjacent (23%) to distant (19%) fingers of the same hand. Sensations of pressure were more markedly suppressed but the gradients were similar. Movement of the opposite hand and isometric contraction of the forearm muscles had little effect. Local anaesthetic blocks of the median and other upper limb nerves counteracted most of the inhibitory effect of movement on cutaneous flutter sensation. We conclude that sensory gating is largely restricted to the moved digits, that it applies to submodalities of both flutter and pressure and that sensory gating is mostly mediated by cutaneous receptor input from the hand.
