title: Immediate effects of digit amputation on SI cortex in the raccoon: unmasking of inhibitory fields.
abstract: Immediately after removal of one digit, inhibitory receptive fields were revealed in the affected part of somatosensory cortex. These were usually seen as 'off' responses if only a short, tapping stimulus is used. Over the course of several weeks, these inhibitory responses disappear and are replaced by excitatory responses. These changes are seen with both alpha-chloralose and barbiturate anesthesia.
