From where does it receive one of its main inputs

he amygdala receives input directly from sensory thalamus, hippocampus (via multiple projections), entorhinal cortex, sensory association areas of cortex, polymodal sensory association areas of cortex, and from various midbrain and brainstem arousal systems via the RAS. The amygdala processes and determines the emotional value of simple sensory input, complex multisensory perceptions and complex cognitive abstractions, even responding specifically to complex, socially relevant stimuli. In turn, the amygdala orchestrates the response to this emotional information by sending projections to brain areas involved in motor (behavioral), autonomic nervous system and neuroendocrine area of the CNS. In a series of landmark studies, LeDoux and colleagues have demonstrated the key role of amygdala in 'emotional' memory.
