title: [AMYGDALA: NEUROANATOMY AND NEUROPHYSIOLOGY OF FEAR].
abstract: This work describes neuroanatomical and neurophysiological mechanisms of Pavlovian fear conditioning, focusing on contributions of the amygdala, a subcortical nuclear group, to control of conditioned fear responses. The mechanisms of synaptic plasticity at projections to the amygdala and within amygdala were shown to mediate the formation and retention of fear memory. This work reviews current data on anatomical organization of the amygdala, as well as its afferent and efferent projections, in respect to the role of the amygdala in auditory fear conditioning during which acoustic signals serve as the conditioned stimulus.
