Term information

The transient fetal subplate zone, together with the marginal zone and the cortical plate, represents the developmental anlage of the mammalian cerebral cortex. It serves as a waiting compartment for growing cortical afferents; its cells are involved in the establishment of pioneering cortical efferent projections and transient fetal circuitry, and apparently have a number of other developmental roles. The subplate zone is a phylogenetically recent structure and it is most developed in the human brain. Subplate neurons are among the first generated neurons in the mammalian cerebral cortex [1]. These neurons disappear during postnatal development and are important in establishing the correct wiring [2][3] and functional maturation [4] of the cerebral cortex. Subplate neurons appear to be selectively sensitive to injury (such as hypoxia) which in humans are associated with motor and cognitive defects
