Neural patterning in the embryonic period is a complex process that involves the establishment of regional identities and the differentiation of neural progenitor cells into specific cell types. Here are key points regarding neural patterning in the embryonic period: 1. Regional Specification : o During the embryonic period, regional specification of the neural tube occurs, leading to the formation of distinct brain regions with unique identities. o The neural tube gives rise to the forebrain (prosencephalon), midbrain (mesencephalon), and hindbrain (rhombencephalon), which further differentiate into specific structures within each region. o Graded patterns of molecular signaling in the neocortical proliferative zone contribute to the regional elaboration of the brain, establishing primitive patterning of sensorimotor regions by the end of the embryonic period. 2. Genetic Patterning : o Genetic signaling pathways play a crucial role in neural patte
