Document Summary

Ex: coincidence detector neuron detects an ap that took 850 ms to travel from left cochlear nucleus. & 600 ms to travel from right cochlear nucleus. *action potentials have to meet closer to right cochlear nucleus. Ex: if start at right cochlear nucleus before left cochlear nucleus. 1- right cochlear nucleus start & left cochlear still at (cid:1004) s. 2- at (cid:1006)(cid:1009)(cid:1004) s = left cochlear nucleus start. 3- at (cid:1010)(cid:1004)(cid:1004) s = left cochlear nucleus (cid:449)ould ha(cid:448)e mo(cid:448)ed (cid:1008)(cid:1009)(cid:1004) s. *not enough time for left cochlear nucleus to catch up: interaural level difference ild - sound localization. *another way to locate sound in addition to itd. Difference in level-intensity b/w sound arriving at 1 ear vs other ear. * because head acts as obstacle & block sound waves. 1- if sound from left side = more loud /intense for left ear than right ear. 2- if sound from right side more loud /intense for right ear than left ear.
