What is a Cytoarchitectonic area?
Cytoarchitecture (Greek κύτος= “cell” + ἀρχιτεκτονική= “architecture”), also known as cytoarchitectonics, is the study of the cellular composition of the central nervous system’s tissues under the microscope.
Where is the cortical?
The cerebral cortex is the outer covering of the surfaces of the cerebral hemispheres and is folded into peaks called gyri, and grooves called sulci. In the human brain it is between two and three or four millimetres thick, and makes up 40 per cent of the brain’s mass.
What is a neo cortex?
Abstract. The neocortex is a complex brain structure that commands higher functions, such as sensory perception, emotion, and cognition.
What is the function of neocortex?
The neocortex is the center for higher brain functions, such as perception, decision-making and language. Our group focuses on the mechanisms governing neocortex development, with a strong interest on the role and regulation of the neural stem cells.
What is a neocortex in psychology?
Neocortex: The newer portion of the cerebral cortex that serves as the center of higher mental functions for humans. The cells in the neocortex are arranged in six layers, within which different regions permit vision, hearing, touch, the sense of balance, movement, emotional responses and every other feat of cognition.
What is a pyramidal?
adjective. of, relating to, or shaped like a pyramid: the pyramidal form. of the nature of a pyramid; pyramidlike.
Which is the correct definition of the term cytoarchitecture?
cy·to·ar·chi·tec·ture. The arrangement of cells in a tissue; e.g., the arrangement of nerve cell bodies in the brain, especially the cerebral cortex. cytoarchitecture. the typical pattern of cellular arrangement within a particular tissue or organ, as in the cerebral cortex. cytoarchitectural, adj.
What makes up the cytoarchitecture of the brain?
Thus, a combination of radial migration and tangential migration, either directed or non-directed, generates a cytoarchitecture composed of both excitatory and inhibitory neurons despite the separate origins of these neurons. These effects disturb the brain cytoarchitecture.
Who is the founder of cerebral cytoarchitecture?
Defining cerebral cytoarchitecture began with the advent of histology—the science of slicing and staining brain slices for examination. 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.
How is the cytoarchitecture of the raphe described?
Cytoarchitecture: These two caudalmost nuclei in the raphe are described together as they have little features distinguishing them apart from their cytoarchitecture and topography ( Bowker et al., 1982; Glazer et al., 1981; Harding et al., 2004 ).
