left hemispheres
is responsible for sensations and movements of
the left side of the body.
right hemispheres
Where two hemispheres communicate through
corpus callosum

right brain dominant person
Each cerebral hemisphere is divided into four lobes:
Frontal, Temporal, Occipital and Parietal
is at work when you talk, move, reason out, and problem solving.
