When participants performed a visual search task, functional MRI responses in entorhinal cortex exhibited a sixfold periodic modulation by gaze-movement direction. The orientation of this modulation was determined by the shape and orientation of the bounded search space. These results indicate that human entorhinal cortex represents visual space using a boundary-anchored grid, analogous to that used by rodents to represent navigable space.

人类内嗅皮层使用边界锚定的网格表示视觉空间。

当参与者执行视觉搜索任务时，内视皮质的功能性MRI反应在注视运动方向上表现出六倍的周期性调制。该调制的方向由有界搜索空间的形状和方向确定。这些结果表明，人类内嗅皮层使用边界锚定的网格表示视觉空间，类似于啮齿动物用来表示可导航空间的网格。
