Great video, just one question: how is it that in the primary auditory cortex this region is sentitive to frequencies from 0.5hz to 16hz if the human auditory frequency range is 20-20kHz?
My guess is that inflexible eardrums would not vibrate upon interacting with sound waves as optimally as flexible eardrums, thus dampening the downstream effects leading to lower volume and possibly difficulty differentiating between different sound frequencies.
@@usernameisgood it would be a form of ‘conductive hearing loss’ as the cochlear is unaffected. Like already mentioned, the stiffening of the ear drum would lead to atypical conduction of the mechanical waves from the ear drum to the cochlear -> reduced perception of sound. Hearing aids can optimise the sound waves for his specific hearing difficulties and reduce his overall hearing loss. Especially if he has one that impacts his social or learning development.
I am not trying to be a troll honest. My question is as follows: since hair cells are specialized receptor cells wouldn't they fire a receptor potential to release their neurotransmitter rather than an action potential? I am not trying to be a douche tool, honest. I am just confused.
So they're not actually receptor cells like for example retinal cells are, so they don't trigger a receptor potential, they do fire a proper action potential :)
The hair cells release neurotransmitter in response to changes in membrane potential, which then goes on to depolarise spiral ganglion cells which fire AP
i am doing research into things that can cause hearing impairments. One thought is ... can an inflamation around the cochlea intermittently disrupt the function of the cochlea.. in varias degrees.. and this inflamtion can effect one or two sides to varying degrees causing the auditory processing to continually be trying to learn / decod correctly what is being said.. causing a pseudoform of hearing loss.. at the same time allowing for "normal" hearing test results which do not tease out the mis decoding of of auditory languange and the complex filtering out of sound.. essentially leving a peron deaf, but with abilityh to hear sound.
My uncle grew up having recurrent ear infections and has atypical hearing (auditory processing disorder) now, as well as generally less sensitivity to sound (hearing loss). He’s not outright deaf, but recurrent inflammation definitely impacted his hearing development.
@@Ann963 does he also have any tinnitus? I have multi tonal varying tinnutus that creates a background noises that makes it additionally harder to decipher (audio process) auditory language. the tinnutus i have is more in the high range which causes disruption of decoding words with the high pitch sounds. I have to rapidly try to guess at words and also continue to hear the rest of what is being said.. it is essentially impossible to do.
Very interesting, and clearly explained. Thank you!
Nice video, but I believe it is tonotopic, not tono-typical
yes :)
This video was helpful so thank you :)
this is so fascinating
Uh, I'm pretty sure those numbers on the auditory cortex are in Khz, not Hz (as the ear can only sense above 20Hz).
amazing! Thank you>

Good question, i must ask if that is only a section of the primary auditory cortex?
He meant kHz.
so is place coding in the basilar membrane and temporal coding in the brain?
I stopped at 5:24 (future reference)
I have auditory processing disorder 😰
Question! I have a son who was once diagnosed with ear drums that were NOT flexible.. How does this affect his auditory processing??

Andrew Graziano what in the world is a receptor potential

Common language more easier interpretation than more high structural like name plc, etc, trus maunya apa, sina
