In addition, the Honeycomb Maze enables researchers to study the correlation of
spatial navigation performance with the activity of place cells in the hippocampus where there is a map of an animal's location in space.
Results show that direct stimulation of the entorhinal area successfully improved hippocampal - dependent memory across a wide range of memory tasks (verbal recall,
spatial navigation, face - name memory, and person / object recognition) with stimulation site (entorhinal white / gray) as the critical determinant of subsequent memory
performance independent of antiepileptic medication (on / off), side (left / right) or type (macro / micro) of stimulation.
