    brain responsible for development of fear and anxiety is key to developing suitable treatments for the wide range of human anxiety disorders. The extended amygdala is a macrostructure in the forebrain that includes three key players in fear and anxiety-like behaviors: the basolateral nucleus of the amygdala(BLA)‚ central nucleus of the amygdala (CeA)‚ and bed nucleus of the stria terminalis (BNST). The BLA sends excitatory projections to both CeA and BNST‚ which in turn project to brainstem structures
