When i found this video, I literally wanted to cry in joy because in my doctoral course, I had a hard time understanding this concept and my preceptor did not explain this well. i immediately shared this video to my future colleagues in our group chat because i know this would be helpful for them as well. I have a much better understanding on this concept now.THANK YOU!
We're talking about the left superior olivary nucleus, right? this means that it is "reached" by neurons coming from the left before those coming from the right (which form the trapezoid body). This means that if the sound comes from ahead, the informations coming from both ears won't reach the left nucleus at the same time (in the video they reach 1 and 5 simultaneously, then 2 and 4 and finally 3 and 3). I thought left one would reach 1 first, then 2 while right one just got to 5... does it make sense? isn't there a delay in the neural pathways aswell?
All I know is that the Pinna (the ear) is capable of selectivly filtrering the frequencies of incoming soundwaves so that it more high frequency conponents get relayed from an elevated soundsource than from one at the level of the ear. I have no idea how the central processing of that information works though
Humans have a diminished localization when it comes to the vertical plane. although there is one mechanism that maps this out. and thats the shape of our outer ears. sound bounces around differently depending on the location of origin. this colors the sound and our brain converts this coloration into spatial data. the coloration has been mapped to some extent, but note that every ear is unique so the coloration will vary from person to person. this same coloration helps with more precise localization in the horisontal plane as well.
Close your eyes, plug your right finger into your right ear and snap your left fingers in front of you, then right then above your head. You are still able to localize the sound.
Some of what you are saying about the ears has some truth, but the full truth is completely missing, in my very humble opinion. The pinna is the only visible organ that you can see how it works as long as you comprehend the true function of the pinna, the only function of the pinna is to infuse binaural information to the ear canal, if the head had no pinna, there would be no binaural information and the perceived sound experience would be heard in side the head, the pinna with binaural infusion gives us the experience of sounds outside the head. The pinna help us to experience the sounds perceived as external with perceived direction for most sounds, pure tones can cause confusion due to standing waves..
this theory (developed from studies on birds) is no longer thought to be true for mammals - see Grothe et al.; Mechanisms of Sound Localization in Mammals; Physiol Rev 90, 2010

who came here from Miledown deck
👋
How did your MCAT go?😂
Here from AnKing😂❤️
@@jdub204 im so nervous ive just started studying and man there's a LOT I don't know
Videos like yours are a godsend for MCAT prep, thanks!
Amazing explanation and a great teacher. Thank you so much!
Finally! Someone explains this concept in a way no german video could
I was reading a paper on this and didn't quite get it. This clarified everything, thank you for the clear and concise explanation!!
Great explanation! I finally understand delay axon lines!
I clearly understand all of your worlds thank you for such an important imfortation I really appreciate it

this is incredibly helpful. you are an amazing teacher and explained it in a way that was straightforward and clear, thank you!
Perfectly explained. Would be more grateful if you could upload the LSO and MTNB system.
Clear and comprehensive explanation!
If hearing depends on vibrating hair .. would people who suffer from hair loss also suffer from hearing loss? Possibly??
This is amazing
What microphone are you using. Sound is so clear !
this is amazing!!!!!! thank youuu
Thank you for saving my life
Nice explanation, but then how do we know when sound comes from behind, up or down? Or can't we?
All I know is that the Pinna (the ear) is capable of selectivly filtrering the frequencies of incoming soundwaves so that it more high frequency conponents get relayed from an elevated soundsource than from one at the level of the ear.

Thanks this makes so much sense!
Thank you good sir you are amazing!!!
Hey man. Could i just pause and thank you for your great lecture? I mean thank you! very clear.
How about sound behind you? How do we distinguish sound directly in front of us from sound directly behind us?
Thank you, buddy for posting this nice video explanation! You saved me hours before an exam. Bless you. :)
Great explanation!!!!!! 👏
LIFE SAVER !!!
Bless you omfg
Thank you for the explanation!!
I now try put that info into action, thanks 👍
Close your eyes, plug your right finger into your right ear and snap your left fingers in front of you, then right then above your head. You are still able to localize the sound.
THANK YOU
thank you sm!! great video
Thank you Mr ❤❤

What a great explanation!
Thank you for this!! :)
Thank you so much! I finally understand sound localization! :)
GOOD EXPLANATION, BUT HOW IT PROCESS CONTINOUS DELAY
God bless you! This video is super helpful :)
Thanks! Great explanation!
What if left or right ear nerve is defective?
amazing,thank you
Thanks a lot
this video was 👍🏼👍🏼👍🏼👍🏼👍🏼
very well explained! thanks

Thank you!
Great lecture thank you so much!
very nice video. straight to the point and very clear. thank you
thank you sir!
This is great! Thanks
