Perception and SensationSmell!
• Our sense of smell is less impressive than our ability to see
and hear!
How do we smell?
• Molecules from the air reach receptors in your nose • Sniffing enhances aromas
• Receptors send messages to Smell Cortex in the Temporal Lobe (located in brain)• Limbic System as well (memory/emotion)
