WebbWe then consider the mechanism that could underlie synaptic changes and update the hypothesis. Genome-wide association studies have identified a number of schizophrenia risk variants converging on pathways regulating synaptic elimination, formation and plasticity, including complement factors and microglial-mediated synaptic pruning. Webb25 apr. 2024 · Physiology of synaptic pruning. Synaptic pruning plays a crucial role in brain maturation by reducing excessive amounts of synapses developed in utero (Chechik Reference Chechik, Meilijson and Ruppin 1998).The process of pruning is activity dependent, using the principle of ‘use it or lose it’.
