Document Summary

Our sense of smell is our oldest sense. Perception: physical sensing of environment, physiological, relatively objective, learning & experience not required, mental interpretation of environment, psychological, relatively subjective, learning & experience are required. Transduction - taking various stimuli, sensing them, interpreting them into neural impulses, and interpreting stimulus. Only 3% of sensory neurons devoted to smell. Human nose is one of the least sensitive in the animal kingdom. Yet can detect 1 billionth of an ounce of odour. Every living organism has the ability to sense chemicals in its environment. Nose is only place with a direct link between environment and our brain. Chemical neurons are the only ones that get replaced/replenish (every 2-3 months) Smell goes directly to the limbic system (linked with memory and emotion)
