        for manipulation

Answer 1

Neocortex
neocortical subdivisions's 
neural connections not limited to neocortex (subcortical as well)
      *functions are shared/redundant
       throughout other lobes

     1)Aphasia-a striking 
        separation of function
        (being able to write but
