About 55% of the cells in the cat lateral suprasylvian area were truly direction-sensitive to moving light and dark spots. For these cells the preferred direction of stimulus movement was the same for the light and dark spots. The most significant effects of the reversal of stimulus contrast was a change in the strength of the responses. A population of "dark-sensitive" neutrons was found that responded vigorously to the movement of dark spots but only very weakly to the movement of light spots. These neurons were only weakly sensitive to stationary flashing lights and responded with On/Off discharges over the whole of their receptive fields.
猫外侧上薛氏回区域中约55%的细胞对移动的亮斑和暗斑具有真正的方向敏感性。对于这些细胞而言，亮斑和暗斑的刺激运动首选方向是相同的。刺激对比度反转的最显著影响是反应强度的变化。发现了一群“暗敏感”神经元，它们对暗斑的移动反应强烈，但对亮斑的移动反应非常微弱。这些神经元对静止闪烁光的敏感性较低，并且在其整个感受野中以开/关放电的形式做出反应。
