Pruning of unused synapses
WebbBecause the CP plasticity, by definition, also involves modification of sensory pathways with elimination of unused synapses and formation of new ones, the capacity for synaptogenesis and synapse pruning has been thought to be involved intricately in mechanisms of postnatal cortical plasticity.
