Direct hippocampal pathway.

 

The entorhinal area (ENT) (layerIII) projects directly (1) into CA1 pyramidal neurons, which innervate (2) the subiculum(sub). Subicular axons project back to the deep layers of the entorhinal cortex (3).
The neurons of these layers send axons to the association cortex (4). The direct pathway receives inputs through the perirhinal cortex (5).
