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.

人类内嗅皮层视觉空间的六向编码。

内嗅网格细胞可以绘制局部环境的地图，但是它们在空间导航之外的作用仍然难以捉摸。我们在高度受控的视觉跟踪任务中检查了人类功能性MRI反应，并表明内嗅皮层显示了六倍旋转对称信号编码的视线方向。我们的结果为视觉空间的网格状内嗅代码提供了证据，并提出了内嗅网格系统在沿连续维度编码信息方面的更一般的作用。
