While the left hemisphere is innately predisposed to specialize for languages,there is also evidence of considarate plasticity in the system during the early stages of language development. Children who undergo a left hemispherectomy expirence an initial period of aphasia, but is certain cases, may reacquiere a linguistic system like that of normal children.The plasticity of the brain dicreases with age and with the increasing specialization of the different hemispheres and regions of the brain.
What is brain plasticity and why it is so important?
Neuroplasticity-or brain plasticity- is the ability of the brain to modify its connections or re-wife itself. Without this ability, any brain, not just the human brain, would be unable to develop from infancy through to adulthood or recover from brain injury.
What makes the brain special is that, unlike a computer, it processes sensory and motor signals in parallel. It has many neural pathways that can replicate another’s function so that small errors in development or temporary loss of function through damage can be easily corrected by rerouting signals along a different pathway.
