The first (SI) and second (SII) somatosensory cortical areas were ablated in one group of cats after preliminary learning of tactile differentiation of rough and smooth surfaces of the floor coating in a special chamber. Somatosensory areas were ablated in another group after learning an adequate choice of the reinforcement side in response to a bell and a metronome. Unilateral and bilateral ablation of SI affected but little the elaboration and achievement of the above acts. Unilateral and bilateral ablation of area SII resulted in a sharp impairment of the tactile differentiation of the surfaces (35% correct responses after unilateral and 26% after bilateral ablation) and a less pronounced disturbances in the choice of the side of reinforcement in response to the bell and the metronome (80% of correct choice after unilateral and 72% after a bilateral ablation.
在一组猫于特殊实验箱中对地板涂层的粗糙和光滑表面进行触觉辨别初步学习后，切除其第一躯体感觉皮层区（SI）和第二躯体感觉皮层区（SII）。在另一组猫学会对铃声和节拍器做出反应并正确选择强化侧后，切除其躯体感觉区。SI区的单侧和双侧切除对上述行为的形成和完成影响较小。SII区的单侧和双侧切除导致表面触觉辨别能力急剧受损（单侧切除后正确反应率为35%，双侧切除后为26%），并且在对铃声和节拍器做出反应时选择强化侧的干扰不太明显（单侧切除后正确选择率为80%，双侧切除后为72%）。
