1:36 A medicine professor at my university explained to me that the amplitude of a stimulus is actually measured via a combination of the frequency of action potentials and the number of activated fibers.. Don't know who's right, but thanks for the video anyway.
@@lefrog3851 Honestly, I'm not at all embodied in the matter anymore, was quite surprised upon reading my own comment to be honest ^^' I did try to get a bit back into it just now, however, and the explanation of my professor at the time seems reasonable to me. I remember (and also saw that on Wikipedia just now) that the pitch is perceived by activation of hair cells located at different positions on the cochlea. If pitch perception was in fact determined only by the location of the hair cells and not by the frequency of action potentials, then both the number of activated fibers as well as the frequency of activation could contribute to the sensation of volume. This is just my rather poorly informed two cents on that however, I hope I did not create more confusion by stating something entirely wrong.
Thanks for replying,I didn't expect it to be honest since you commended 2 years ago :P .After searching for answers I can say I didn't find any definite answer,some say both phase locking and location code cooperate which I find very confusing but since this model you described makes more sense I am gonna call it a day and stick with that.Thanks again for taking the time to comment!!
@@lefrog3851 My pleasure, did actually take some effort to orientate myself again :). Appreciate your reply back as well, let's hope we got it somewhat right. Have a nice day!
great video! at 1:29 there is word i can't make out which refers to the way neurons fire at random phases at high frequencies. Could you please spell it so we look it up?
concerning PLL induction heater i have a very important question WOULD YOU please answer it ? how can we make sure pll has locked and is working properly? when i turn it on , it gets a soft start from high to low frequency until it stops on a pre tuned frequency while i have current and inverter voltage in phase but as the work peace gets to the curie point i don't see any change in the amount of the frequency . it remains the same as when i started while the current leads the voltage. would you please explain exactly what happens at resonance on the oscilloscope from when you start until the work peace gets to the curie point?? in face will you see the frequency goes higher as the work peace gets hotter and the current and voltage remain the same ?? thanks a lot Saeed Mahdav
Thanks a ton for this. It's an immense relief to find something like this short and to the point video when I'm cramming for an exam :)
thanks sansa stark !
I thought the exact same thing!
Exactly omg😂

Confused about this too!I just can't understand how phase locking fits to all of this.Did you find any satisfactory answer?

your voice is amazing
finally i understand! :D thanks a lot for this!
oh my god, your voice and accent is just the cutest!!:)
The best explanation. tnx a lot. all the best
great video! at 1:29 there is word i can't make out which refers to the way neurons fire at random phases at high frequencies. Could you please spell it so we look it up?

Can i use your video (citing you of course) for a presentation i m doing as part as the MSc of Neuroscience?
concerning PLL induction heater i have a very important question WOULD
YOU please answer it ?
how can we make sure pll has locked and is working properly?
when i turn it on , it gets a soft start from high to low frequency
until it stops on a pre tuned frequency while i have current and
inverter voltage in phase but as the work peace gets to the curie point i
don't see any change in the amount of the frequency . it remains the
same as when i started while the current leads the voltage.
would you please explain exactly what happens at resonance on the
oscilloscope from when you start until the work peace gets to the curie
point??
in face will you see the frequency goes higher as the work peace gets
hotter and the current and voltage remain the same ??
thanks a lot Saeed Mahdav
I see Exploring the Brain by Bear, Connors and Paradiso was your primary source :D Nice explanation though!
all hail the queen in the north
the queen in the north!! the queen in the north!! the queen in the north!!
Hi, may I ask for transcript please? Anyone?
this is fabulous i love you thanks jessica griffiths can i be your friend please make more videos can i have your autograph
Georgie Holiday congrats on being my first fangirl
PogU
HAHAHAHAH THIS SOUNDS LIKE SANSA
