Development of the thalamus: From early patterning to regulation of cortical functions.
The thalamus is a brain structure of the vertebrate diencephalon that plays a central role in regulating diverse functions of the cerebral cortex. In traditional view of vertebrate neuroanatomy, the thalamus includes three regions, dorsal thalamus, ventral thalamus, and epithalamus. Recent molecular embryological studies have redefined the thalamus and the associated axial nomenclature of the diencephalon in the context of forebrain patterning. This new view has provided a useful conceptual framework for studies on molecular mechanisms of patterning, neurogenesis and fate specification in the thalamus as well as the guidance mechanisms for thalamocortical axons. Additionally, the availability of genetic tools in mice has led to important findings on how thalamic development is linked to the development of other brain regions, particularly the cerebral cortex. This article will give an overview of the organization of the embryonic thalamus and how progenitor cells in the thalamus generate neurons that are organized into discrete nuclei. I will then discuss how thalamic development is orchestrated with the development of the cerebral cortex and other brain regions. This article is categorized under: Nervous System Development > Vertebrates: Regional Development Nervous System Development > Vertebrates: General Principles.
期刊介绍:
Developmental biology is concerned with the fundamental question of how a single cell, the fertilized egg, ultimately produces a complex, fully patterned adult organism. This problem is studied on many different biological levels, from the molecular to the organismal. Developed in association with the Society for Developmental Biology, WIREs Developmental Biology will provide a unique interdisciplinary forum dedicated to fostering excellence in research and education and communicating key advances in this important field. The collaborative and integrative ethos of the WIREs model will facilitate connections to related disciplines such as genetics, systems biology, bioengineering, and psychology.
The topical coverage of WIREs Developmental Biology includes: Establishment of Spatial and Temporal Patterns; Gene Expression and Transcriptional Hierarchies; Signaling Pathways; Early Embryonic Development; Invertebrate Organogenesis; Vertebrate Organogenesis; Nervous System Development; Birth Defects; Adult Stem Cells, Tissue Renewal and Regeneration; Cell Types and Issues Specific to Plants; Comparative Development and Evolution; and Technologies.
