Subplate Neurons Foster Inhibition
Previous work demonstrates an essential role of subplate neurons during ocular dominance (OD) column formation in the developing visual cortex. While inhibitory circuitry has also been shown to play an essential role in OD plasticity, the relationship between subplate neurons and the development of inhibitory circuits has been unclear. In this issue of Neuron, Kanold and Shatz provide evidence ...
متن کاملSynaptogenesis in purified cortical subplate neurons.
An ideal preparation for investigating events during synaptogenesis would be one in which synapses are sparse, but can be induced at will using a rapid, exogenous trigger. We describe a culture system of immunopurified subplate neurons in which synaptogenesis can be triggered, providing the first homogeneous culture of neocortical neurons for the investigation of synapse development. Synapses i...
متن کاملMolecular diversity of early-born subplate neurons.
Subplate cells in the mouse are generally defined as cells located in the subplate layer between the white matter and layer 6a. They are some of the earliest born and maturing cells of the cerebral cortex. The postnatal subplate layer in mouse contains neurons with expression of the presynaptic protein complexin 3 (Cplx3), connective tissue growth factor (CTGF), the orphan nuclear receptor Nr4a...
متن کاملSubplate Neurons Regulate Maturation of Cortical Inhibition and Outcome of Ocular Dominance Plasticity
Synaptic plasticity during critical periods of development requires intact inhibitory circuitry. We report that subplate neurons are needed both for maturation of inhibition and for the proper sign of ocular dominance (OD) plasticity. Removal of subplate neurons prevents the developmental upregulation of genes involved in mature, fast GABAergic transmission in cortical layer 4, including GABA r...
متن کاملSelective vulnerability of subplate neurons after early neonatal hypoxia-ischemia.
Neonatal hypoxia-ischemia in the preterm human leads to selective injury to the subcortical developing white matter, which results in periventricular leukomalacia (PVL), a condition associated with abnormal neurodevelopment. Maturation-dependent vulnerability of late oligodendrocyte progenitors is thought to account for the cellular basis of this condition. A high frequency of cognitive and sen...
