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
