The extent of any modularity, or specialization of brain function by area, remains under [[investigation]]. If a specific region of the brain, or even an entire hemisphere, is either [[injured]] or destroyed, its [[functions]] can sometimes be assumed by a neighboring region in the ipsilateral hemisphere or a corresponding region in the contralateral hemisphere, depending upon the area damaged and the patient's age. When [[injury]] [[interferes]] with pathways from one area to another, alternative (indirect) [[connections]] may develop to [[communicate]] [[information]] with detached areas, despite the inefficiencies. | The extent of any modularity, or specialization of brain function by area, remains under [[investigation]].
