Early-generated preplate neurons in the developing telencephalon: inward migration into the developing striatum

Cerebral Cortex

Abstract

Specialized subsets of early-generated neurons provide the cellular cues that are necessary for the establishment of characteristic cell and fiber interactions in each brain region. During the development of the mammalian cerebral cortex, the early-generated cells line up in the most superficial part of the telencephalic pallium forming the preplate. It has been generally thought that the preplate derivatives are exclusively located in the cortical region and govern the early histogenetic phase of cortical development. However, we here disclose an unexpected evidence that a subset of early-generated neurons of the piriform preplate migrate inward into and disperse within the subcortical structure striatum during the embryonic stage. Their migratory route is unique and its direction is opposite to the ordinary migration of neuronal precursors directed outward from the periventricular germinal zone. After immigrating into the developing striatum, these early-generated cells are closely associated with the intrastriatal fascicules of axons. The majority of these cells are eliminated by apoptotic cell death during the early postnatal stage. Based on these findings, we propose a new concept: the preplate neurons may not only direct ...Continue Reading

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
