Protomap hypothesis

Webb3 aug. 2024 · How category-specific regions of cortex, or ‘domains’, in the primate ventral stream arise is unclear. In this Perspective, Arcaro and Livingstone present a ‘bottom-up’ … 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…

Intimately related to the RUH is the 'protomap' hypothesis, which states that the primordial identity of each functional area of the cerebral cortex is encoded within the cortical stem cells prior to the formation of the cortical layers. Within each developing radial unit, the process of neurogenesis gives rise to post-mitotic (non-dividing) cortical neurons, which begin the process of radial neuronal migration from the ventricular zone and adjacent subventricular zone to form the cortical … WebbPROTOMAP stands for PRotein TOpography and Migration Analysis Platform and was invented and developed by Ben Cravatt and colleagues at The Scripps Research … haukun luonnollinen ruokinta https://aminokou.com

Our second hypothesis was that within periods there are significant differences in the relative growth rate (i.e., percent increase per GW) between neighboring regions.
