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 … Webb31 jan. 2006 · of neocortical transcriptional patterning has provided a dataset that reinforces the prevailing dogma of the protomap hypothesis and provides a foundation from which molecular insights can be drawn.
