NEET (UG) 2023 — Question 150
The parts of the human brain that help in the regulation of sexual behaviour, expression of excitement, pleasure, rage, fear, etc. are:
- Option A:
corpora quadrigemina and hippocampus
- Option B:
Brain stem & epithalamus
- Option C:
Corpus callosum and thalamus
- Option D:Correct
Limbic system & hypothalamus
Answer: D
Step-by-step solution
Regulation of sexual behaviour and emotional reactions such as excitement, pleasure, rage and fear is a function associated with the limbic system together with the hypothalamus. Option D names the limbic system and the hypothalamus, so it is correct. Option A is wrong because corpora quadrigemina is a midbrain reflex centre, even though the hippocampus is part of the limbic system. Option B is wrong because the brain stem and the epithalamus are not involved in emotional regulation. Option C is wrong because the corpus callosum is a tract connecting the cerebral hemispheres and the thalamus is a sensory relay centre. Therefore, the correct answer is D.
