Chapter 5 Questions
1. Give examples of people (and their applications) interested in a better understanding of chemo-sensory systems:
2. What are some reasons for pursuing research in biorobotics:
3. What is olfaction?
4. What is gustation?
5. Why is it difficult to differentiate olfactory and gustatory sensing systems?
6. _____ The best way to distinguish between olfaction and gustation is
a) olfaction is simple, and gustation is complex
b) olfaction is a distance sense, and gustation is a contact sense
c) olfaction detects chemicals in air while gustation detects chemicals in fluids
d) there is no difference between the two
7. Photoreceptors are the first neurons in the visual processing system pathway. What are the first neurons in the olfactory system pathway?
8. The retinotopic map (vision) and somatotopic map (touch) in the brain provides a spatial map of external to stimuli in the respective systems. How is the olfactory system receptive field mapped in the brain?
9. Taste buds provide neuronal inputs to what type of cells?
