Potential role for microRNA regulation in the tuning of engram recruitment during fear memory consolidation
Emotions play an adaptive role in shaping neural representations of strong aversive memories. Complex mood disorders like post-traumatic stress disorder (PTSD), depression and anxiety share common symptoms of memory impairment, though their link to mechanisms of memory consolidation is not well understood. The strength of ensemble formation in micro- and macro-circuits between the central nucleus of the amygdala (cea) and the hypothalamic paraventricular nucleus (pvn) facilitates associations between different internal states, innate behaviour and aversive experiences. Understanding how ensemb
