Webb15 mars 2013 · • It is plasticity that enables the process of developing and pruning connections, allowing the brain to adapt itself to its environment. 11. • Because of axonal sprouting and synaptic pruning that lend to neural plasticity, damage to the brain or other aspects of the nervous system is not always permanent. Webb28 jan. 2024 · This process is mediated by the insertion of AMPA receptors containing a GluA1 subunit into the synapse, which is followed by a replacement of these receptors with GluA1 lacking AMPA receptors. Therefore, the presence of GluA1 acts as a signal of recent learning-induced plasticity in the brain.
