Pruning and plasticity
Webb24 sep. 2024 · Synaptic pruning is a process that occurs in the brain during development. It is a form of neuroplasticity, which is the ability of the brain to change and adapt to new … WebbNeuroplasticity is different from neurogenesis. Neuroplasticity is basically making or pruning synapses based on experience (i.e. long term potentiation or Hebbian Learning) Neurogenesis is “growing” new brain cells which probably happens a bit in adults but we’re unsure about how important these new cells actually are to cognition

Webb28 jan. 2016 · Microglia can prune unnecessary synapses and axon terminals during postnatal development and adaptation to novel environments, which plays important role in synaptic remodeling [36, 37]. These studies imply that both central sensitization and synaptic plasticity are involved in learning and memory through the activities of glial cells. WebbRAG-1 is one of the most studied enzymes in the adaptive immune system as it is responsible for the high diversity (in the range of 10 14) of T Cell Receptors (TCR) and B Cell Receptors (BCR). The biological function of RAG-1 is to cut Variable, Diversity, and Joining (VDJ) gene segments located on several chromosomes (Fig. 2) [31, 32].These …
