Comment: Structures of the limbic system are found in a rim
that encircles the diencephalon. Two temporal lobe structures,
the hippocampal formation with its pathway, the fornix, and the
amygdala and its two pathways, the stria terminalis and ventral
amygdalofugal pathway send projections into the hypothalamus and
septal region in a C-shaped course. The septal nuclei project to the
habenular nucleus via the stria medullaris thalami. The cingulate,
prefrontal, orbitofrontal, entorhinal, and periamygdaloid cortical areas
interconnect with subcortical and hippocampal components of the
limbic forebrain and are often considered part of the limbic system.
The limbic system is the substrate for regulation of emotional
responsiveness and behavior, for individualized reactivity to sensory
stimuli and internal stimuli, and for integrated memory tasks.
