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]
BA10 was originally defined broadly in terms of its cytoarchitectonic traits as they were observed in the brains of cadavers, but because modern functional imaging cannot precisely identify these boundaries, the terms anterior prefrontal cortex, rostral prefrontal cortex and frontopolar prefrontal cortex are used to refer to the area in the ...
In the human brain, the anterior cingulate cortex (ACC) is the frontal part of the cingulate cortex that resembles a "collar" surrounding the frontal part of the corpus callosum. It consists of Brodmann areas 24 , 32 , and 33 .
Brodmann area 12 is a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. [ 1 ] [ 2 ] It occupies the most rostral portion of the frontal lobe . Brodmann-1909 did not regard it as homologous , either topographically or cytoarchitecturally, to rostral area 12 of the human.
The modulatory functions are primarily found in the rostral sector of the reticular formation and the premotor functions are localized in the neurons in more caudal regions. The reticular formation is divided into three columns: raphe nuclei (median), gigantocellular reticular nuclei (medial zone), and parvocellular reticular nuclei (lateral zone).

Rostral and caudal: rostral refers in general anatomy to the front of the body (towards the nose, or rostrum in Latin), and caudal refers to the tail end of the body (towards the tail; cauda in Latin). The rostrocaudal dimension of the brain corresponds to its length axis, which runs across the cited flexures from the caudal tip of the spinal ...
Brodmann area 11 is a subdivision of the frontal lobe of the guenon monkey defined on the basis of cytoarchitecture (Brodmann-1905). Distinctive features: area 11 lacks an internal granular layer (IV); larger pyramidal cells of sublayer 3b of the external pyramidal layer (III) merge with a denser self-contained collection of cells in the internal pyramidal layer (V); similar to area 10 of ...
