Document Summary

The timing of the sound waves matches the rate of firing of neural impulses to the brain. Soundwaves move hair cells in the ear. The closer to the eardrum you are, the higher the pitch (20,000hz) The travelling wave in cochlea matches the pitch/wave coming into the cochlea. Firing of action potential replicates each of the peaks. Cochlear implants help to restore hearing, but not fully. Sound arrives to the near ear first. Sound arriving to the near ear is louder. Sound is arriving to near ear louder and disperses around the head to get to the other ear. Animals like bunnies are able to localize sound better than we are. Problems with the outer and middle ear. Problems with the inner ear and/or central auditory system. Dots on tongue are related to different sets of chemicals (sweet, sour, etc. ) No receptors (taste buds) on the centre of the tongue.
