NROC64H3 Lecture Notes - Lecture 4: Vestibular Duct, Ventral Cochlear Nucleus, Dorsal Cochlear Nucleus
Document Summary
Lecture 4 the auditory system and the vestibular system. Short answer question: describe the three pathways of the visual system that are differently specialized for motion, color and shape, magnocellular pathway, motion, parvocellular pathway fine detail, koniocellular pathway, non specific. Introduction sense of hearing: audition, detect sound, perceive and interpret nuances sense of balance, vestibular system, head and body location, head and body movements. Hearing and balance: why so close together? lateral line organs small pits or tubes function sense vibration or pressure changes. Overview the structure of the auditory system: physiology of the cochlea, auditory pathways, how the brain encodes intensity and frequency the auditory cortex sound localization. The structure of the auditory system: auditory system diagram, slide 9 tympanic membrane, pinna, auditory canal, ossicles, oval window cochlea. Early auditory pathway stages sound waves tympanic membrane: ossicles, oval window cochlea fluid, movements of basilar and tectorial membranes, sheering forces sensory neuron response.
