1. (16 pts) A speciаlized cell type in а speciаlized envirоnment mediates bоth auditiоn and vestibular senses. What are the similarities and differences between these two sensory systems? Your answer should include: i) the frequency ranges covered by the two senses with a mechanistic explanation for the reasons for the non-overlapping ranges; ii) the mechanical, ionic and synaptic mechanism(s) mediating the transduction of physical forces to afferent action potential frequency; iii) identifying which of the two systems uses cell-based, active amplification, with an explanation of how that amplification works; and iv) the biochemical mechanisms, including ion channels and other proteins, of adaptation that occurs in this cell type. 2. (4 pts) You examine a patient with profound hearing loss and find no obvious problems in their outer or middle ear. The patient was a former construction worker who did not regularly wear hearing protection. Given this information, what is the likely cause of the hearing loss and is this damage repairable? You suggest a cochlear implant which directly electrically stimulates the auditory nerve at different positions along the cochlea. What do these different positions normally represent? The most advanced implants have 24 locations of stimulation, but many have only 3. Yet many patients that receive even the 3 electrode implants report relatively normal hearing after a while. What principle of information coding in the nervous system does this demonstrate? Give an example of such coding in the visual system.
