PA student here, this video was very helpful!! I hope you continue to make educational videos!

Thank you so much for sharing this along with Phosphofructokinase II information. So far in reading biochemistry books, this is one of the most difficult concepts for me to get just from reading, and this really helps thank you.

Thanks for your video. I, however, confused. It is claimed in the video that horizontal cell inhibits the centre photoreceptor. Then, why do we say that horizontal cells mediate lateral inhibition? I would be grateful if you could shed some light on this

سبحان الله

I want to learn more about HCNchannel which moves both at the state of depolarization and hypolarization.

thank you so much!! this was way more helpful than my 2 hour lecture

you are the best! arigatou gozaimasu :)

Inactivation gate is also H gate correct?

❤❤

Considering the fact that the target is large and the retina cells are small I am pretty certain that this pseudointellectual explanation is the erroneous construct of some physiologist or group with a large ego and small mind giving their lab results too heavy a credence. Sorry , but I'm right.

Wow!

I have a question, how does photoreceptor decide whether it will be connected to a Bipolar ON or Bipolar OFF type, the video explains the working given either of the connection. Can a photoreceptor be connected to more that one Bipolar cell? Thanks

That was really awesome. Thank You

Neuroscience student here. Very well explained. I didn't quite understand what was causing the directionality of an action potential so I'm glad I watched this.

😍 thank you. this video is amazing

Thank you so much for your precise speaking and the clear illustrations. I subscribed and liked your page.

Thank you for this

This is just amazing! Excellent presentation

So it's basically Electrical Engineering Control System. It's amazing to see that engineering starts from the human body itself or otherwise a Human body is a perfectly engineered system

omg i finally get it

Thank you and yes please more of this. I would like to know more about theee other channels!

tysm

So how does this get affected by pyrethrins? Like why would the channels be kept open? I was reading about shock dope lol I’m just curious as to what is happening in the brain that ordinary flowers can’t derive the same compound from, like how chrysanthemums can make pyrethrum for pesticides after undergoing a process

What an animation 🔥 concept clearned in 3:20 mins

really helpful! I'm having my biochemistry of glucides and lipids exam in 3 days and I have problems figuring out their regulation :(

Hi Laura this REALLY helped me understand the AP firing line and how it works I hope you make many many more..... Kind regards

This helped me , THX ❤❤❤❤❤❤

amazing video

THANK YOU SOOO MUCH !!!!

Beating my head around this topic ended with this explanation. Thank you so much!!

Thank you so much for this video saved me so much headache.

Great animation and explanation - thank you for spreading your knowledge!:)

To better understand this subject you need to go back to the research conducted by Hubel and Wiesel during the second half of the 20th Century. That was the foundation that lead to an understanding for the visual system. Their initial paper was published back around 1960 when I was in Jr. High School. I became interested in the subject in the mid to late 1960s and built an "artificial retina" using an IBM 1620 Computer a couple of years later.

Very clearly explained. Thank you ❤

please make more nervous system videos!

I’d like to see more. Love seeing how they worked. Trying to visualise how densely packed they are with each other and if there is differing density’s on the axon, maybe more near the end?

🤍

Wonderful video, just what I needed before my exam this week! Thank you!

At minute 2:32 it said that on on bipolar cell it gets depolarize. But, should it be the opposite? Depolarize on off dipolar cell?

this shit is fire!

Why does the number of sodium ions increase within the cell when the neuron is receiving an excitatory signal? Isn’t that a result of the gated channels opening?

Well Done! One of the best videos I have seen.

Love your explanation. Thank you so much!

PFK--2 the side piece chyck when wifey PFK-1 busy at work

thanks for this great explanation

Just Wonderful! 👏👏👏

helo, i thought it was backwards? on depolarizes and OFF hyperpolarizes?

Ignoring horizontal cells is bad. Plus i don't think they only release gaba to the center cones, they do it with all cones or rods?

Thank you so much, your video is very helpful. I am studying how DDT, insecticide, affects insect evolution. Namaste :)

Please can you talk about the Synaptic organisation of the retina
