• THE EMOTION AND MEMORY COMPONENTS OF THE LIMBIC
  SYSTEM

2
emotional feelings and expression, includes a)
cortical part of emotion system    anterior
cingulate gyrus medial prefrontal cortex
         orbitofrontal gyri    b) amygdala (key
integrator and grader of incoming sensory
information c) ventral or limbic basal ganglia
ventral striatum (nucleus accumbens) ventral
pallidum (output nucleus) d) dorsomedial nucleus
of thalamus e) hypothalamus - nodal point in
organizing visceral somatic emotion responses.
  The emotions structures are connected by
bundles of fibers that include   the cingulum
(cortico-cortical connections)   the ventral
amygdalofugal path (VAPF) for input/output of the
amygdala   the stria terminalis (for
communication of the amygdala with the septal
area and hypothalamus   -   the medial forebrain
bundle (MFB), the multifunctional ascending and
descending tract in the lateral hypothalamus
