The inhibitory components in the neuronal responses of the cat's lateral suprasylvian area (LSA) to moving bright and dark stimuli were investigated. The LSA neurons could be divided into two groups. Neurons of the first group (33%) do not reveal spatial displacement of the inhibitory zones and show displacement of the discharge centers in the receptive field only for one polarity of contrast of moving stimuli, either brighter or darker than the background. The second group (67%) contained the neurons which showed a spatial displacement of the inhibitory components and discharge centers in the receptive field for either polarity of contrasts of the moving stimuli. Tested with stationary flashing stimuli, the majority of neurons in both groups had overlapping ON-OFF discharge regions within their receptive fields. The results obtained with moving stimuli of different speeds and with the masking method suggest the rebound origin of the inhibitory responses in LSA neurons.
对猫外侧上薛氏回区域（LSA）神经元对移动的亮暗刺激的反应中的抑制成分进行了研究。LSA神经元可分为两组。第一组神经元（33%）未显示抑制区的空间位移，仅在移动刺激的对比度的一种极性（比背景亮或暗）下，其放电中心在感受野中发生位移。第二组（67%）包含的神经元在移动刺激的两种对比度极性下，其感受野中的抑制成分和放电中心均发生空间位移。用静止闪烁刺激进行测试时，两组中的大多数神经元在其感受野内具有重叠的开-关放电区域。用不同速度的移动刺激和掩蔽方法获得的结果表明，LSA神经元的抑制反应起源于反弹。
