After extinction, fear memories are not erased rather they are inhibited. This inhibition of fear is limited to the extinction context, and fear memory returns or “renews” outside of the extinction context. It has been suggested that a hippocampal – prefrontal – amygdala circuit is involved in the contextual regulation of extinguished fear memories. In this talk I will present recent experiments using anatomical disconnections and functional retrograde tracing that map the neural circuit for fear renewal in rats. These data reveal that projections from both the ventral hippocampus and prelimbic cortex to the basolateral amygdala are necessary for the renewal of fear after extinction.
