Hippocampus and auditory input

I am a master's student.  
My current understanding of hippocampal connectivity to the rest
of the brain (in rat) is this:  entorhinal cortex collects input
from many sensory cortical areas (a "cold" sensory input), and
relays it to hippo.  Subcortical inputs, e.g., LC, reticular 
formation, septum/dBB, hypothalamus, modulate the hippo.'s
processing in "motivational" and "arousal" ways.

I am trying to understand how hippo. output affects the rest of 
the brain, and behavior.  I know that a rat with a missing
hippo. does not perform well on some learning tasks, and I have
some familiarity with cognitive mapping work.

What is the function of the hippocampus?  I'd appreciate comments
and references.
