The amygdala is an almond-shaped group of nuclei found deep and medially within the temporal lobes of the brain. Known to be the area of the brain responsible for emotional reaction, but plays an important role in processing of memory and decision making as well. It is part of the limbic system.
The prefrontal cortex has been defined based on cytoarchitectonics by the presence of a cortical granular layer IV.It is not entirely clear who first used this criterion. Many of the early cytoarchitectonic researchers restricted the use of the term prefrontal to a much smaller region of cortex including the gyrus rectus and the gyrus rostralis (Campbell, 1905; G. E. Smith, 1907; Brodmann ...
The dorsomedial prefrontal cortex (dmPFC [1] [2] or DMPFC [3] [4] is a section of the prefrontal cortex in some species' brain anatomy.It includes portions of Brodmann areas BA8, BA9, BA10, BA24 and BA32, [5] although some authors identify it specifically with BA8 and BA9.
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain.The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans.

The development of the cerebral cortex, known as corticogenesis is the process during which the cerebral cortex of the brain is formed as part of the development of the nervous system of mammals including its development in humans. The cortex is the outer layer of the brain and is composed of up to six layers.
The Brodmann area 32, also known in the human brain as the dorsal anterior cingulate area 32, refers to a subdivision of the cytoarchitecturally defined cingulate cortex. In the human it forms an outer arc around the anterior cingulate gyrus .
The hippocampal subfields are four subfields CA1, CA2, CA3, and CA4 that make up the structure of the hippocampus.Regions described in the hippocampus are the head, body, and tail, and other hippocampal subfields include the dentate gyrus, the presubiculum, and the subiculum.
Gyrification in the human brain. Gyrification is the process of forming the characteristic folds of the cerebral cortex. [1] The peak of such a fold is called a gyrus (pl. gyri), and its trough is called a sulcus (pl. sulci).
