The memory centers that dopamine effects are called the amygdala and hippocampus. The amygdala contains the amygdaloid nuclei‚ which plays an important role in the modulation of mood (Mervaala et al.‚ 2000). The amygdala itself is an expanded region at the tail of the caudate nucleus and participates in the expression of emotions‚ control of behavioral activities‚ and development of moods (McKinley‚ 2006).

Damage to the amygdala leads to the inability to make memories in relation to the emotional or ‘valence’ of events. In this paper I will review the 1) structure‚ 2) functional pathways‚ 3) physiology‚ 4) development‚ and 5) the interesting role of PKMzeta in the amygdala. PKMzeta inhibits a critical pathway in the amygdala which appears to block the establishment of painful

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

In a study done at the University of Pittsburgh‚ the team conducting the experiments noticed that lower amygdala volumes could cause drastic differences in whether an individual was more likely to become aggressive‚ violent or even behave psychopathic. It was found to be three times more likely‚ verses normal leveled amygdala volumes. But independent factors
