Hippocampal mechanisms involved in the enhancement of fear extinction caused by exposure to novelty

This 2014 Brazilian rodent study provided more information on the workings of the hippocampus. The researchers measured the effects of re-experiencing a fear within a specific context:

“Within a restricted time window, a brief exposure to a novel environment enhances the extinction of contextual fear.

The enhancement of extinction by the exposure to novelty depends on hippocampal gene expression..on hippocampal but not amygdalar processes..”
