This week we will examine the chemical sense of smell (olfaction) and taste. This is a two-part discussion
question (part one pertaining to olfaction and part two pertaining to taste) and both parts must be answered in
order to receive full credit. Discuss the components of the olfactory system: the olfactory receptors, the olfactory sensory neurons, the olfactory bulb
and the cortex. Then, discuss what kinds of evidence support the idea that different people may have different taste experiences. What mechanisms might be responsible for these differences? Lastly, explain the role of culture in the development of smell and taste and provide two examples of how culture could account for
variation in perception.
