Brain recalls old memories via new pathways

Shift in fear retrieval circuitry eyed in anxiety disorders – NIH-funded studies

quirkfearmemory_148987_1.png
Although rats’ behavior did not change over time following fear conditioning, the underlying circuitry activated to retrieve the fear memory shifted, perhaps increasing its staying power. An initial circuit from the pre-limbic prefrontal cortex (PL) to the basolateral amygdala (BLA) was supplanted, a week later, by a circuit to the central amygdala (CeA) via the paraventricular nucleus of the thalamus (PVT). It’s thought that the PVT may serve to integrate fear with other adaptive responses. The discovery may provide clues to improved treatments for anxiety disorders.
