Answer:
a. All of the above
Explanation:
The idea of localization of brain function  is underscores by the fact that; certain regions of the brain are designated to  coordinate particular  functions  of  the brain. Thus behaviour is controlled by certain parts, emotions by specific  parts, sleep and wastefulness  by another parts etc .E.g  a region in the frontal part of the left cerebral  hemisphere called Broca  area is localized  as the speech center of the brain.This was proposed  by Paul Broca, and  it formed the beginning of the concept of localization of the brain.
Its application is in the tracing of disease or malformation of brain functions. thus if an individual is  manifesting certain neurological  disorder, with the aid of neuroimaging techniques, the specific brain region localized  for the condition can easy be traced for effective management.
