Concept:The olfactory lobe is the brain region responsible for receiving and processing smell impulses.
Explanation:The olfactory lobe is located on the underside of the forebrain.
It receives sensory impulses from the olfactory receptors in the nose.
These impulses are then interpreted as different smells.

The cerebrum handles conscious thought, reasoning, and general sensation.
The cerebellum coordinates balance and voluntary muscle movements.
Therefore, smell is specifically linked to the olfactory lobe.
