Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Contralateral Organisation refers to:
A
Each lobe of the brain being responsible for movement and sensation in the opposite side of the body.
B
Each hemisphere (left or right) of the brain being responsible for movement and sensation in the opposite side of the body.
C
Each section of the brain being responsible for movement and sensation in the opposite side of the body.
D
Each hemisphere (left or right) being responsible for cognitive input in the opposite side of the body.
Explanation: 

Detailed explanation-1: -The contralateral organization of the forebrain (Latin: contra‚ against; latus‚ side; lateral‚ sided) is the property that the hemispheres of the cerebrum and the thalamus represent mainly the contralateral side of the body.

Detailed explanation-2: -/ˌkɒn.trəˈlæt. ər. əl/ on or affecting the opposite side of the body: A stroke affecting the right side of the brain may cause contralateral paralysis, affecting the left arm and leg.

Detailed explanation-3: -Thus, our model suggests that the left hemisphere provides predictive control mechanisms specifying aspects such as movement direction to movements of both the contralateral and the ipsilateral arms, while the right hemisphere contributes positional control mechanisms during movements of either arm as well.

Detailed explanation-4: -Each hemisphere controls muscles and glands on the opposite side of the body (i.e. the right side of the brain or hemisphere controls the left side of the body.)
