Q.

The parts of human brain that helps in regulation of sexual behaviour, expression of excitement, pleasure, rage, fear etc. are:

  1. A

    Limbic system and hypothalamus

  2. B

    Corpora quadrigemina and hippocampus

  3. C

    Brain stem and epithalamus

  4. D

    Corpus callosum and thalamus

Solution

The limbic system together with the hypothalamus governs emotional behaviour — pleasure, rage, fear, sexual behaviour and motivation. The corpora quadrigemina belong to the midbrain reflex relay; the corpus callosum connects the two cerebral hemispheres; the thalamus is a sensory relay station — none of these are the seat of emotional behaviour.
