The hippocampus is located in the central region of the brain forming a spiral of interconnected soma (cell bodies) as illustrated to the right.  In humans the number of layers along the spine of the hippocampal structure is estimated to be 40 million.  Studies of traumatic damage within this region suggest that the hippocampus is associated with temporal or episodic perception and short to medium term memory.

The hippocampus consists of layers of rings arranged in a spiral configuration.  Signals received from the cortical spinal tracts and thalamus propagate through each lateral segment of this spiral structure, presenting a temporal history of the efferent (incoming) patterns.  These temporally distributed patterns subsequently propagate to assembly structures of the neo-cortex.  An analogous structure is provided within HNeT by use of the AllocTemporalCell function.  This structure is applied in the learning and recall of temporally based patterns, such as speech.
