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 ...
Many of our complex behaviors and mental activities require simultaneous engagement of multiple tasks, and they suggest the anterior prefrontal cortex may perform a domain-general function in these scheduling operations. Thus, the frontopolar cortex shares features with the central executive in Baddeley's model of working memory.
Brodmann area 46, or BA46, is part of the frontal cortex in the human brain.It is between BA10 and BA45.. BA46 is known as middle frontal area 46.In the human brain it occupies approximately the middle third of the middle frontal gyrus and the most rostral portion of the inferior frontal gyrus.
Brodmann mapped the human brain based on the varied cellular structure across the cortex and identified 52 distinct regions, which he numbered 1 to 52. These regions, or Brodmann areas, correspond with diverse functions including sensation, motor control, and cognition. [1]

Brodmann area 9, or BA9, refers to a cytoarchitecturally defined portion of the frontal cortex in the brain of humans and other primates. Its cytoarchitecture is referred to as granular due to the concentration of granule cells in layer IV. [1] It contributes to the dorsolateral and medial prefrontal cortex.

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 .
