limbic lobe
Acronym: LML
The term limbic lobe refers to a topologically defined combination of three convolutions of cerebral cortex and one nuclear structure. They form a C-shaped structure on the medial surface of the hemisphere in the human ( Carpenter-1983 ) and the macaque ( Martin-2000 ). The convolutions (subcallosal gyrus, cingulate gyrus and archicortex) surround the corpus callosum, rostrally, dorsally and caudally. The archicortex, in addition, separates it from the thalamus ventrocaudally. Ventrorostrally, the nuclear structure, ( the amygdala) separates it from the overlying striatum and pallidum, Viewed from the midline, the most prominent components are the subcallosal gyrus, cingulate gyrus, and parahippocampal gyrus.They largely obscure the hippocampal complex, which is by far the largest part of the otherwise vestigial archicortex in the primate.
      Functionally, the lower limb of the limbic lobe is involved in attention to, identification of and memory of stimuli. upper limb is more involved in evaluation and contol of response to stimuli ( Bowden-2021 ).
