在麻醉和瘫痪的成年猫的纹状皮质中，研究了静态和运动纹理图案的神经元反应。纹理图案由呈现在细胞兴奋性感受野中的中心光条和周围许多类似元素的阵列组成。对于静态条件，周围的元素平行或正交于中心线（方向测试）。对于移动条件，中心和环绕元素（都在相同的方向）在相同或相反的方向上移动（运动测试）。36%（31/86）的运动神经元和24%（24/99）的定向神经元对显示特征对比度的图案的反应比对均匀图案的反应更强烈。这些神经元可以形成方向和运动的视觉弹出的神经基础。版权所有（C）1997 Elsevier Science Ltd.
Neuronal responses to static and moving texture patterns were investigated in the striate cortex of anaesthetized and paralysed adult cats. Texture patterns were composed of a central light bar presented in the excitatory receptive field of a cell and an array of many similar elements in the surround. For the static condition, elements in the surround were either parallel or orthogonal to the centre line (orientation test). For the moving condition, centre and surround elements (all at same orientation) moved either in the same or in the opposite directions (motion test). Thirty-six percent (31/86) of the neurons tested for motion and 24% (24/99) of the neurons tested for orientation responded more strongly to the patterns displaying feature contrast than to the uniform patterns. These neurons may form a neural basis for visual pop-out of orientation and motion. Copyright (C) 1997 Elsevier Science Ltd.
