Sensory perception and movement, as well as complex cognitive functions such as language, thought and memory, are made possible by the interlinkage of serial and parallel processing in different brain regions.2 Damage to a single specific area therefore may not result in the complete loss of a cognitive function or faculty; the affected function may eventually at least partially return once the undamaged parts of the brain reorganize the connections between themselves.2
