The part of the brain that interprets smell is the olfactory bulb.  This brain structure is usually above the nasal cavity and below  frontal lobe.
Olfaction or the sense of smell involves chemicals. The receptors for smell are the olfactory hair cells located on the roof of each nasal cavity in a path of cells called the olfactory epithelium or membrane. Odors or scents chemical vapors. Chemoreceptor cells (neurons) perceive the chemicals as they vaporize. Olfactory receptors in the nose: chemoreceptors. - Taste receptors on the tongue: chemoreceptors. - Skin receptors: tactile, mechano, thermo, nociceptors. 2. Visceroreceptors: sensory receptors that produce sensations from organs or internal tissues. - Sensations include pain, hunger, thirst, fatigue or nausea.
