Unformatted text preview: rve (cochlear nerve) Auditory nerve forms part of 8th cranial nerve Continuing the Auditory Continuing the Auditory Pathway governs hearing and balance Cochlear nerve axons enter brainstem at the level of the medulla, synapse in cochlear nucleus Cochlear nucleus sends connections to superior olive and trapezoid body Superior Olive Superior Olive Ventral cochlear nucleus cells project to nuclei in medulla called the superior olive. Where differences timing and loudness of the sound in each ear are compared Helps determine the direction the sound came from. Interaural Time differences Binaural Cues Binaural Cues
Interaural Time Difference (ITD) biological binaural cue is the splitsecond delay between the time when sound from a single source reaches the near ear and when it reaches the far ear. Interaural Amplitude (intensity) Difference (IAD) Sound amplitude and pressure differences between each ear Inferior Colliculus Inferior Colliculus Located below superior colliculi visual processing centers Relays ascending auditor...
