有一种可能性已经被探讨过，即视觉皮层中一个生理上可识别的细胞子集特别适合于立体深度信息的处理。首先，概述了对这种处理有用的视差检测器的特性。然后，设计了一种从皮质细胞中获得详细双目反应数据的方法。此外，还开发了一个视差检测器模型，其中包括皮层细胞的合理分层排列。来自细胞的数据与原型视差检测器的要求比较好，并且与模型的预测非常一致。这些结果表明，一种特定类型的皮层神经元表现出视差检测器所期望的特征。
The possibility has been explored that a subset of physiologically identifiable cells in the visual cortex is especially suited for the processing of stereoscopic depth information. First, characteristics of a disparity detector that would be useful for such processing were outlined. Then, a method was devised by which detailed binocular response data were obtained from cortical cells. In addition, a model of the disparity detector was developed that includes a plausible hierarchical arrnagment of cortical cells. Data from the cells compare well with the requirements for the archetypal disparity detector and are in excellent agreement with the predictions of the model. These results demonstrate that a specific type of cortical neuron exhibits the desired characteristics of a disparity detector.
