A.
The left side of the body.
B.
The right side of the body.
C.
The lower half of the body.
D.

Explanation / Answer
1. B. The right side of the body
Motor cortex on the left side of the brain controls the right side of the body. So any damage to the left motor cortex will affect the right side of the body
2. C. Intelligence
Intelligence is linked to the thickness of the cerebral cortex of the brain, which plays a key role in memory, thought, language and consciousness.
3. D. death
Since it carries out the vital functions like heart beat and breathing, damage to the medulla will most likely result in death.
4. C. depression
Serotonin deficiency is found to have direct correlation with depression and anxiety
5. B. Schizophrenia
Higher-than-average levels of dopamine and/or increased sensitivity to dopamine have been associated with Schizophrenia.
