What area of the brain controls smell?
Olfactory Cortex
The Olfactory Cortex is the portion of the cerebral cortex concerned with the sense of smell. It is part of the Cerebrum. It is a structurally distinct cortical region on the ventral surface of the forebrain, composed of several areas. It includes the piriform lobe and the hippocampal formation.
