1. A patient complains that visual images appear and disappear randomly in their vision. You give a visual test and determine that everything in the patient’s left visual field is missing/not being perceived. What can you infer about the location along the central visual pathway that has been disrupted to produce this deficit pattern? How did you come to that conclusion?
2. Describe how the otolith organs of the vestibular system encode information about head acceleration and deceleration into neural signals.
3. Describe how cochlear hair cells depolarize and send signals to spiral ganglion cells.
4. Describe how the duration of a sensory stimulus is coded in neural activity sent to the brain.
5. Define the concept of sensory threshold and what it means when someone has an elevated sensory threshold.
6. Describe the relationship between the density of sensory receptors, the size of receptive fields, and sensory discrimination.
