WebHow does the process of myelination and synaptic pruning affect neural processing quizlet? Myelination continues, synaptic pruning occurs, the brain’s need for O2 is … WebNeuronal activity promotes the formation and maturation of myelin sheaths (1–6), processes that are mechanistically reminiscent to synaptogenesis (7). Like synapses, myelin sheaths are pruned after formation (8). However, we know almost nothing about the mechanisms that underlie myelin pruning.

WebOne theory of why many brains are synaptically pruned when a human or other primate grows up is that maintenance of synapses consume nutrients which may be needed elsewhere in the body during growth and sexual maturation. This theory presupposes no mental function of synaptic pruning. Web27 mrt. 2024 · Myelination is the process of coating the axon of each neuron with a fatty coating called myelin, which protects the neuron and helps it conduct signals more efficiently. Myelination begins in the brain stem and cerebellum before birth, but is not completed in the frontal cortex until late in adolescence. processing materials
