Non-visual senses Flashcards
Soundwaves// doppler effect
car horn: closer it gets the higher the pitch is
Amplitude
the magnitude of a soundwave (decibels)
Complexity
single frequency: simple
multiple frequency: complex
Ossicles (middle ear)
3 bones that transmit vibration from the tympanic membrane to the oval window
Study anatomy of middle ear
(malleus, incus, stapes)
Ossicles 2 function
amplify vibrations and protect inner ear from loud noises
Anatomy of Ear
Tympanic membrane (eardrum), malleus, incus, stapes(stirrup), oval window
Oval Window
portion of the cochlea attached to the stapes// transmits vibrations to the fluid in the cochlea
Cochlea
snail shell// smaller structure of the inner ear
look @ the tale of two streams
anterior stream
identifying the sounds or the “what” pathway
- Goes from the auditory cortex to the prefrontal cortex
Posterior stream
located sounds or the “where” pathway
-goes from the auditory cortex to the posterior parietal cortex
Nerve damage in middle brain can lead to what
conductive damage to the cochlea
chemical sense
taste and smell
Auditory Cortex
tonotopically organized. (spacial arrangement where sound is percieved)
