Special Issue Information

Dear Colleagues,

The six-layered structure of the cerebral cortex consists of neurons born in the ventricular zone, arranged in orderly layers according to the time of their birth date. An accurate understanding of the mechanisms of neuronal migration is fundamental to understanding the development of the neocortex and the pathogenesis of developmental neurological disorders. New neurons are generated in the ventricular zone in the developing cerebrum and then migrate to their final destination to function. Abnormalities in the migration of neurons during development cause abnormalities in the structure and function of the neocortex, leading to a variety of disorders such as epilepsy and developmental disorders.

During migration, neurons sense various extracellular environmental signals, including biochemical and mechanical cues, and behave in response to these signals. Gene networks and signaling pathways involved in neuronal migration have been identified using various methods. More recently, it has been shown that the earliest-born subplate neurons in the subplate layer facilitate migration mode conversion in radial neuronal migration.

This Special Issue aims to gain a better understanding of the signaling systems that control the developmental process of the cortex and the mechanisms that regulate cell migration.

Abstract
Early regional patterning and laminar position of cortical projection neurons is determined by activation and deactivation of transcriptional factors (TFs) and RNA binding proteins (RBPs) that regulate spatiotemporal framework of neurogenetic processes (proliferation, migration, aggregation, postmigratory differentiation, molecular identity acquisition, axonal growth, dendritic [...] Read more.
Early regional patterning and laminar position of cortical projection neurons is determined by activation and deactivation of transcriptional factors (TFs) and RNA binding proteins (RBPs) that regulate spatiotemporal framework of neurogenetic processes (proliferation, migration, aggregation, postmigratory differentiation, molecular identity acquisition, axonal growth, dendritic development, and synaptogenesis) within transient cellular compartments. Deep-layer projection neurons (DPN), subplate (SPN), and Cajal–Retzius neurons (CRN) are early-born cells involved in the establishment of basic laminar and regional cortical architecture; nonetheless, laminar dynamics of their molecular transcriptional markers remain underexplored. Here we aimed to analyze laminar dynamics of DPN markers, i.e., transcription factors TBR1, CTIP2, TLE4, SOX5, and RBP CELF1 on histological serial sections of the human frontal cortex between 7.5–15 postconceptional weeks (PCW) in reference to transient proliferative, migratory, and postmigratory compartments. The subtle signs of regional patterning were seen during the late preplate phase in the pattern of sublaminar organization of TBR1+/Reelin+ CRN and TBR1+ pioneering SPN. During the cortical plate (CP)-formation phase, TBR1+ neurons became radially aligned, forming continuity from a well-developed subventricular zone to CP showing clear lateral to medial regional gradients. The most prominent regional patterning was seen during the subplate formation phase (around 13 PCW) when a unique feature of the orbitobasal frontal cortex displays a “double plate” pattern. In other portions of the frontal cortex (lateral, dorsal, medial) deep portion of CP becomes loose and composed of TBR1+, CTIP2+, TLE4+, and CELF1+ neurons of layer six and later-born SPN, which later become constituents of the expanded SP (around 15 PCW). Overall, TFs and RBPs mark characteristic regional laminar dynamics of DPN, SPN, and CRN subpopulations during remarkably early fetal phases of the highly ordered association cortex development.
