Abstract
The area V6A of the medial parieto-occipital cortex of the macaque is studied for gaze sensitivity. The reported experimental observations support the computational theory of the gain fields to produce a distributed representation of the real position of targets in head-centered coordinates. Although it was originally pointed out that the majority of the cells exhibit roughly linear gain fields [1] [2], we have verified that the peak-shaped gaze fields reported in this study are not in contrast with the gain field models developed in the theoretical neuroscience literature [3] [4]. Rather, the use of peak-shaped (e.g., non monotonic) gaze fields even improves the efficiency of the coding scheme by reducing the number of units that are necessary to encode the target position.
