Subplate zone (brain)

From Wikipedia, the free encyclopedia

The transient fetal subplate zone, together with the marginal zone and the cortical plate, represents 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 phylogenetically recent structure and it is most developed in the human brain.
