Both these classes of cells differentiate into many different types generated with highly specialized functions and shapes. Within the neural tube stem cells generate the 2 major classes of cells that make the majority of the nervous system : neurons and glia. Failure of these opening to close contributes a major class of neural abnormalities (neural tube defects). The early central nervous system begins as a simple neural plate that folds to form a groove then tube, open initially at each end. This development generates the most complex structure within the embryo and the long time period of development means in utero insult during pregnancy may have consequences to development of the nervous system.
Neural development is one of the earliest systems to begin and the last to be completed after birth. The adult hippocampus is associated with memory (contextual and working), emotional reactivity and the hypothalamus- pituitary- adrenal (HPA) axis function.
The cortical hem is the source for 2 patterning signals Wingless-related ( WNT) and bone morphogenetic protein ( BMP). Brain parcellation The assembly and organization of these regions is vital for human behavior and perception, as evidenced by the prevalence of area-specific phenotypes that manifest in neurodevelopmental and psychiatric disorders.Recent studies have shown that secondary brain vesicle ( telencephalon) dorsomedial region described as the "cortical hem" is involved with hippocampus development.
