Xochitecatl [ʃot͡ʃiˈtekat͡ɬ] is a pre-Columbian archaeological site located in the Mexican State of Tlaxcala, 18 km southwest of Tlaxcala city. [1] The major architecture dates to the Middle Preclassic Period (1000–400 BC) but occupation continued, with one major interruption, until the Late Classic , when the site was abandoned.
Defining cerebral cytoarchitecture began with the advent of histology—the science of slicing and staining brain slices for examination. [2] It is credited to the Viennese psychiatrist Theodor Meynert (1833–1892), who in 1867 noticed regional variations in the histological structure of different parts of the gray matter in the cerebral hemispheres.
With its medial boundary corresponding approximately to the rhinal sulcus it is located primarily in the fusiform gyrus.Cytoarchitecturally it is bounded laterally and caudally by the inferior temporal area 20, medially by the area 35 and rostrally by the temporopolar area 38 (H) (Brodmann-1909).
Brodmann area 23 is a subdivision of the cerebral cortex of the guenon defined on the basis of cytoarchitecture. Brodmann regarded it as topographically and cytoarchitecturally homologous to the combined ventral posterior cingulate area 23 and dorsal posterior cingulate Brodmann area 31 of the human (Brodmann-1909).
It is bounded caudally by the angular area 39 (H), rostrally and dorsally by the caudal postcentral area 2, and ventrally by the subcentral area 43 and the superior temporal area 22 (Brodmann-1909). Cytoarchitectonically defined subregions of rostral BA40/the supramarginal gyrus are PF, PFcm, PFm, PFop, and PFt. Area PF is the homologue to ...
The region encompasses most of the ventral temporal cortex, a region believed to play a part in high-level visual processing and recognition memory. This area is also known as inferior temporal area 20 , and it refers to a subdivision of the cytoarchitecturally defined temporal region of cerebral cortex.
Distinguishing features according to Brodmann-1905: in contrast with area 6 of Brodmann-1909 the cortex of area 32 is relatively thick; the transition from cortex to white matter is more gradual; the distribution of cells is less dense; and there is no distinct boundary between the inner pyramidal layer (V) and the multiform layer (VI); it is ...
Brodmann areas are based on cytoarchitectonic parcellation using numbering associated with locations in the brain to illustrate functional activity. BA 22 is separated from the primary and secondary auditory cortex by using cytoarchitectonic parcellation. [ 2 ]
