These results illustrate that (1) GRP system(s) can significantly affect the expression of learned fear, (2) some of the relevant brain sites mediating these effects include the PrL, IL and the CeA, and (3) such effects may be dependent upon whether responses were evoked by environmental contextual fear cues or by specific auditory cues that were explicitly paired with an aversive stimulus.

It appears that manipulation of GRP at the BLA may influence the expression of learned fear and that these effects preferentially influence contextual versus cue-dependent emotional responses.
