Consistency of Spatial Representations in Rat Entorhinal Cortex Predicts Performance in a Reorientation Task.

Goal-directed behavior can be affected by environmental geometry. A classic example is the rectangular arena reorientation task, where subjects commonly confuse opposite but geometrically identical corners [1]. Until recently, little was known about how environmental geometry shapes spatial representations in a neurobehavioral context [2] (although see [3]).
