In chronic experiments on alert cats the discharges of neurons in the secondary projection zone of the somato-sensory cortex to click and electrical stimulation of contralateral paw were investigated. 57% of neurons responded to "specific" stimulation by increasing the discharge frequency, 18%--by weakening or stopping the background activity, while 25% did not react at all. 30% of neurons responded by activation to the "non-specific" stimulation (click), 25%--by inhibition and 45% were unresponsive. An investigation of intersensory convergence by sending signals from different analyzer systems showed that bimodal responses are peculiar to most neurons (55%) of this zone. 18% of neurons with a response only to the "specific" or "non-specific" stimuli were found. It is suggested that polysensory convergence on the neurones of the somato-sensory cortex is important for the cortical area in the process of closing of conditioned connections.
在对清醒猫进行的慢性实验中，研究了体感皮层二级投射区内神经元对点击声和对侧爪电刺激的放电情况。57%的神经元通过增加放电频率对“特异性”刺激做出反应，18%的神经元通过减弱或停止背景活动做出反应，而25%的神经元根本没有反应。30%的神经元通过激活对“非特异性”刺激（点击声）做出反应，25%的神经元通过抑制做出反应，45%的神经元无反应。通过发送来自不同分析器系统的信号对感觉间汇聚进行的研究表明，该区域的大多数神经元（55%）具有双峰反应。发现18%的神经元仅对“特异性”或“非特异性”刺激有反应。有人认为，体感皮层神经元上的多感觉汇聚在条件连接闭合过程中对皮层区域很重要。
