WebbInvestigating the protomap hypothesis in the primate cerebral cortex; EPH A receptor expression The cerebral cortex, the seat of consciousness and intelligence, is mapped out into functional areas; for instance vision, movement control and language are controlled by distinct areas that are the same across normal individuals. Webb1 apr. 2024 · The cerebral cortex is divided stereotypically into a number of functionally distinct areas. According to the protomap hypothesis formulated by Rakic neural …

Gene networks controlling early cerebral cortex arealization

WebbEarly thalamus-independent steps in the process of cortical arealization take place on the basis of information intrinsic to the cortical primordium, as proposed by Rakic in his … The Protomap is a primordial molecular map of the functional areas of the mammalian cerebral cortex during early embryonic development, at a stage when neural stem cells are still the dominant cell type. The protomap is a feature of the ventricular zone, which contains the principal cortical progenitor cells, known as radial glial cells. Through a process called 'cortical patterning', the protomap is patterned by a system of signaling centers in the embryo, which provide positional i… in memory cache c# .net core

Gene networks controlling early cerebral cortex arealization

Webb3 juli 2024 · Protomap is patterned through cortical patterning by signaling centers in the embryo which provides the positional and cell fate instruction. These early genetic … WebbThe protomap hypothesis was opposed by the protocortex hypothesis, which proposes that cortical proto-areas initially have the same potential, and that regionalization in large part is controlled by external influences, such as … WebbA large body of evidence now supports the “protomap” hypothesis, according to which cues that specify particular areas act on cortical progenitor cells. Some of these cues … in memory butterfly svg
