拔除一个手指后，立即在躯体感觉皮层的受影响部分显示抑制性感受野。如果只使用短的敲击刺激，这些通常被视为“关闭”反应。在几周的过程中，这些抑制性反应消失，并被兴奋性反应所取代。这些变化在α-氯阿洛糖和巴比妥酸盐麻醉中都可以看到。
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.
