Entorhinal grid cells map the local environment, but their involvement beyond spatial navigation remains elusive. We examined human functional MRI responses during a highly controlled visual tracking task and show that entorhinal cortex exhibited a sixfold rotationally symmetric signal encoding gaze direction. Our results provide evidence for a grid-like entorhinal code for visual space and suggest a more general role of the entorhinal grid system in coding information along continuous dimensions.
内嗅皮层网格细胞映射局部环境，但它们在空间导航之外的参与仍然难以捉摸。我们在一项高度受控的视觉跟踪任务中检查了人类功能磁共振成像响应，并显示内嗅皮层表现出六倍旋转对称的信号来编码注视方向。我们的结果为视觉空间的网格状内嗅码提供了证据，并表明内嗅网格系统在沿连续维度编码信息方面具有更普遍的作用。
