Many of those brain areas defined by Brodmann have their own complex internal structures. A simple example of this type of correspondence is the primary motor cortex, a strip of tissue running along the anterior edge of the central sulcus.

Areas de Brodmann by Andrea Gavilanes on Prezi
Different parts of the cerebral cortex are involved in different cognitive and behavioral functions. When von Bonin and Bailey constructed a brain map for the macaque monkey they found the description of Brodmann inadequate and wrote: Electrical stimulation of the cortex at any point causes a muscle-contraction in the represented body part.

Motor areas innervating each part of the body arise from a distinct zone, with neighboring body parts represented by neighboring zones. See more of Neuropsique on Facebook.

Higher order functions of the association cortical areas are also consistently localized to the same Brodmann areas by neurophysiologicalfunctional imagingand other methods e. Recently published MRI-based in vivo myelin content mappings show, with regard to the primary sensory and motor regions, a striking concordance with our map.

Please help improve this section by adding citations to reliable sources. In other projects Wikimedia Commons. Precentral gyrus Precentral sulcus. Here we present a supplementary map in which the overall density of the myelinated fibers in the individual architectonic areas is indicated, based on a meta-analysis of data provided by Adolf Hopf, a prominent collaborator of the Vogts.
Área de Brodmann
Indusium griseum Uncus Amygdala. Visual cortex 17 Cuneus Lingual gyrus Calcarine sulcus. Brodmann areas were originally defined and numbered by the German anatomist Korbinian Brodmann based on the cytoarchitectural organization of neurons he observed in the cerebral cortex using the Nissl method of cell staining. The map also reveals the presence of a number of heavily myelinated formations, situated beyond the primary sensory and motor domains, each consisting of two or more myeloarchitectonic areas.

Visual areas farther downstream extract features such as color, motion, and shape.
brodjann As regards the heavily myelinated clusters shown by our map, scrutiny of the current literature revealed that correlates of all of these clusters have been identified in in vivo structural MRI studies and appear to correspond either entirely or largely to known cytoarchitectonic entities.
The primary visual cortex Brodmann area 17which is the main recipient of direct input from the visual part of the thalamus, contains many neurons that are most easily activated by edges with a particular orientation moving across a particular point in the visual field. These formations were provisionally designated as the orbitofrontal, intraparietal, posterolateral temporal, and basal temporal dark clusters. The resultant map includes myeloarchitectonic areas, 64 frontal, 30 parietal, 6 insular, 17 occipital and 63 temporal.
