Synchronized Anxiety
This is a guest post in our #NPGsfn11 blog series and posted on behalf of Lucas Glover.
In 1999, the functional organization of the hippocampus became a little more complicated. A functional double dissociation was identified (also here) between the two parts of this structure, the dorsal (dHPC) and ventral hippocampus (vHPC.) Since then, much research has focused on the dHPC and its role in spatial memory processing, but much less has been done on the vHPC. The vHPC is known to be involved in mediating anxiety-like behaviors and I sought out a cutting edge update on this proposed functional role here at the Society for Neuroscience Annual Meeting. The emerging story: vHPC and prefrontal cortex (PFC) synchronize to a network oscillation known as ?theta? to regulate anxiety behaviors.
