What is neural pruning?
communication between neighbouring neurons through the movement of neurochemicals across the synapse
the way in which new regions of the cortex take over the localisations of regions that have been damaged
the process by which the brain changes and adapts as a result of experience.
a natural process that occurs in the brain in which synapses that are no longer needed are removed
