Chapter 13 | Sensory Systems
- If a person sustains damage to axons leading from sensory receptors to the central nervous system, which step or steps of sensory perception will be affected?
- In what way does the overall magnitude of a stimulus affect the just-noticeable difference in the perception of that stimulus?
- What can be inferred about the relative sizes of the areas of cortex that process signals from skin not densely innervated with sensory receptors and skin that is densely innervated with sensory receptors?
- From the perspective of the recipient of the signal, in what ways do pheromones differ from other odorants?
- What might be the effect on an animal of not being able to perceive taste?
- How would a rise in altitude likely affect the speed of a sound transmitted through air? Why?
- How might being in a place with less gravity than Earth has (such as Earth’s moon) affect vestibular sensation, and why?
- How could the pineal gland, the brain structure that plays a role in annual cycles, use visual information from the suprachiasmatic nucleus of the hypothalamus?
- How is the relationship between photoreceptors and bipolar cells different from other sensory receptors and adjacent cells?
