BIOL 4041 Midterm: Sensory Physiology Test 3 Review
Document Summary
How to point out sin of an angle on a circle also cosine. What does f and a and theta stand for in sin equation. Inverse square law: how you can use that in eld research. Anatomy of cochlea: uids and membranes, how the membranes work (tectorial and basilar) Frequency tuning: passive mechanics, active mechanics. If a given neuron res, you hear a speci c pitch. Perceive loudness based on frequency of ring of auditory system. Frequency of ring is not related to pitch; instead the pattern of action potentials re ects the sound being experienced. Monday, march 7, 2016: not bursts of ap at 3000 or 4000hz, distinguishing location!! If frequencies are very similar but wave is shifted a little, then brain and best line the waves up to determine time difference and thus location. At low frequency can compute a time difference between ap. Locating sounds: 2 differences in sound that you would experience in each ear.
