Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

If a person has a brain tumor that results in a disruption of his/her eating behavior, which of the following areas is the most likely location of the tumor?

A	hypothalamus
B	thalamus
C	limbic system
D	cerebellum

Explanation:

Detailed explanation-1: -(D) Stimulation of the lateral hypothalamus causes an organism to be hungry, and stimulation of the ventromedial hypothalamus causes an organism to stop eating. The other brain structures listed are not centrally involved in hunger motivation.

Detailed explanation-2: -Because each side of the brain controls movement of the opposite side of the body, damage to the left hemisphere causes weakness on the right side of the body, and vice versa.

Detailed explanation-3: -You have your temporal lobes to thank. The temporal lobes are located in the cerebrum, and they help process audio and visual stimuli. Your temporal lobe has a direct line to the cerebellum by neural pathways, allowing your brain to process stimuli and react quickly – by jumping away from a loud sound, for example.
