We identified a group of neurones in the posterior parietal cortex of the monkey that responded preferentially to a flat stimulus in a particular orientation on a 3D computer graphics display. We designated these neurones surface-orientation selective (SOS) neurones since they showed tuning to the 3D orientation of the surface. Almost all of the SOS neurones were sensitive to binocular disparity and their responses increased with the width or length of the stimulus, but the responses of only some of them decreased with increasing thickness of the stimulus. These results suggest that SOS neurones extract surface orientation signals from the binocular disparity signals and play an important role in the perception of 3D shape and the visual guidance of hand movement.
我们在猴子的后顶叶皮层中识别出一组神经元，它们在三维计算机图形显示器上对特定方向的平面刺激有优先反应。我们将这些神经元称为表面方向选择性（SOS）神经元，因为它们表现出对表面三维方向的调谐。几乎所有的SOS神经元都对双眼视差敏感，并且它们的反应随着刺激的宽度或长度增加而增强，但只有其中一些神经元的反应随着刺激厚度的增加而减弱。这些结果表明，SOS神经元从双眼视差信号中提取表面方向信号，并在三维形状感知和手部运动的视觉引导中发挥重要作用。
