Cytoarchitecture of the cerebral cortex
WebIn the early 1900s, a German neuroscientist named Korbinian Brodmann performed an extensive study of the microscopic anatomy—the cytoarchitecture—of the cerebral cortex and divided the cortex into 52 separate regions on the basis of the histology of the cortex. WebDe novo somatic variants in genes encoding components of the PI3K–AKT3–mTOR pathway, including MTOR, have been linked to hemimegalencephaly or focal cortical dysplasia. Similarly to other malformations of cortical development, this condition presents with developmental delay and intractable epilepsy, often necessitating surgical treatment. …

The Nissl staining technique (named for Franz Nissl the neuroscientist and histologist who originated the technique) is commonly used for determining the cytoarchitectonics of neuroanatomical structures, using common agents such as thionine, cresyl violet, or neutral red. These dyes intensely stain "Nissl bodies" (rough endoplasmic reticulum), which are abundant in neurons and reveal specific patterns of cytoarchitecture in the brain. Other common staining tec… WebThe complete architectonic analysis of an individual living brain has not been achievable to date, because the relationship remains unclear between laminar gray value changes of cerebral cortex in magnetic resonance (MR) images and those of cyto- and myeloarchitectonic histologic sections. We examined intensity profiles through the cortex …
WebDec 12, 2007 · The cortex is covered by intensity line profiles that traverse the cortical ribbon from gray/white boundary to pial surface. The shape of each profile reflects the cytoarchitecture ( Schleicher and Zilles 1990 ). A distance function is computed to determine the degree of similarity of adjacent blocks of line profiles.
