Question

Which of the following statement regarding forebrain is correct?

• A. Forebrain consists of hypothalamus, thalamus and cerebellum.
• B. The layer of cells covering the cerebral hemispheres is referred to as white matter.
• C. The lobe involved in regulation of sexual behaviour and expression of emotional reaction is also a part of the forebrain.
• D. Association areas of the forebrain are sensory in function.

Answer 1

Answer: (C)

The lobe involved in the regulation of sexual behaviour and expression of emotional reaction is the 'limbic lobe'. It is formed by the inner part of the cerebral hemispheres and structures like the amygdala, hippocampus, etc. Hence, it is a part of the forebrain.
The forebrain consists of the hypothalamus, thalamus, and cerebrum.
The layer of cells covering cerebral hemispheres is the cerebral cortex, also called grey matter.
Association areas of the forebrain are neither motor nor sensory in function.
