This is extremely enlightening. I can't believe it took me until Neuro to finally watch this (already took Histo, Physio, and Biochem and no professor could make this clear for me).
Possibly the best video out there that explain vision physiology and phototransduction in particular. Very thorough and virtually a whole chapter in a video. More power!
Taking an intro to neuroscience course and this answered every one of my questions. Thank you so much! Somehow my textbook forgot to mention "why" and "what" happens after the photoreceptors become hyperpolarized. Confused the hell out of me. Now it makes so much sense thanks to your video. Keep up the good work! I look forward to watching your other videos!
Hey man, great content! I did find this particular video somewhat lacking on the topic of ON/OFF bipolar cells (in respect to cones) as well as center/surround field ganglion cells. I think this is a central topic to tackling peripheral visual processing and should at least be mentioned if not explained in detail
Thank you a million times! Finally, I understood! Trying to learn from my textbook and watching the material provided by the instructor is like walking in the dark tunnel and seeing no light. Just got overwhelmed with all those words on the pages and pages of information, and having no clue what they are trying to tell me. Finally, I get it!! Your videos are a blessing, especially for the ones that study from home and try to make sense of the whole small details in a&p!
From the bottom of my heart, God bless you! Thank you for helping me understand what I've been trying to make sense of throughout a whole semester at optometry school lol this and other videos. All your videos from ALL the subjects ROCK!
Hey professor I dont know tyis comment will reach to u or not but im just wanna thanks u from all my heart as u do extreme and extreme hard work for students like us who completely rely on u, May Allah be pleased with you
I came from MCAT khan academy and watched their phototransduction lecture. I wanted to dive deeper into this topic and this video help me accomplish that. Thank you so much.
I'm a vet student and man, this was the finest explanation of this much difficult topic I ever heard. Even well paid profs are not able to break this down so comprehensible.
its crazy how much better I learn from some people on youtube more than college professors paid tens of thousands of dollars to get an education from....gotta love it
Thank you ...This is mind boggling not just from the process itself and how all this has been determined but how it happens fast enough from I understand as essentially diffusion and how it all evolved most probably from a developing light sensitive area on single cellular organism many millions of years ago. Extremely interesting! Pushing the imagination to the limit and beyond!
My professor is not interacting with our online class so these videos are so helpful to me. Thank you for taking the time to explain things in detail. You really make it easy to follow. Great job!
Your channel is amazing!! Please keep posting. If I wasnt a student and/or had at least some disposable income I'd love to become a patron. But for now, a thank you is all i could do. :)
Amazing presentation, Mr. Ninja. I have watched many of your videos to better understand the materials I'm learning in school. Your presentation and mastery of the subject matter is far above any professor I've had. Thank you!
Mate this is brilliant. Im a past bioMed student and recently found the urge to learn about vision in newborn. This has been a fantastic refresher course to help me remember the basics. More people need to be doing this kind of stuff. Youve got a new subscriber 🎉
i want to cry and thankyou and i just want to personally meet you just to say that your efforts and hardwork really matters to us ..thankyou . thankyou so much
This was extremely helpful... i can finally understand this process thanks to you .. u simplified it so well thank u so much ... i can't believe this is available for free ❤
All your videos are outstanding, filled with plenty of information, easy to understand and retain for a longer duration of time... I wish I could get a common like button to hit all at once.. I have not come across even a single that I did not like or could skip watching. Great work done!! Please keep doing what you are doing... Your work is exceptional. (Kindly make videos on biochemistry and more of org-chemistry as stuff overlaps). Look forward to watching more
You are amazing thank you so much! It would have taken me days to understand the mechanisms you described, but you explained it so well in 42 minutes! You are the best!!
I wanted to learn about the function of my eyes and this video helped me i know you love what you do you explained everything Thank you for educating us about our eyes
Reading the phototransduction in my book really made my head wanna explode..this video actually made it very understandable or palatable.. Thank u and continue in your good work.. God bless u
The cones and rods are "inhibitory" cells, and when they are hyperpolarised they cannot inhibit the bipolar cells. The bipolar cells are "excitatory" cells, and when they are not inhibited, they can excite the ganglion cells, and the electric impulse is propagated by the optic nerve to the vision cortex.
U are really really so Great sir...🙏!!! Very complex topics into so simple one 🙏.. ..sir !!not only in one subjects ....you are rocking in all the subjects🔥 ...sir ..real ninja warrior 😎sir!! With great respect from india🛐...💥
amazing video. your video is really understandable. I am an optometrist student and I watch your all ophthalmic related videos. Each video is so nice keep it up sir
I wish I could take ur lectures sitting in front of u... Anyhow... This too is a blessing ☺️... Even for a very minor topic ,, I junmp to ur videos.. as my concept is 100 percent clear after watching the video🌸
I love your lectures! There are no analog systems in the body. Our brains are massively parallel biologically driven digital processors! Our 5 senses are peripheral systems feeding into it. In your Special Senses lecture you illustrated the wiring diagram of the focus and iris servo feedback loops which are critically damped. I love your series!!!
This was by FAR the best explanation of phototransduction; comprehensively reviewing this entire segment from my neurology class nearly 2 years ago. I can't thank you enough for taking the time to make, edit, and post this video!
Six years later and it is still the best on the internet.
THE WAY YOU BREAK DOWN ALL THESE COMPLEX ANATOMICAL STRUCTURES INTO SIMPLER FORMS TO FERCILITATE EASY UNDERSTANDING ... ... ... IT'S TRULY AMAZING !!!
I can't believe I just watched this 42 minute lecture and was engaged the whole time. You are such a great teacher. Thank you so much!
You are literally better than all of the professors in my University
Same experience here. It's frustrating and kind of disappointing. This guy is incredible!!
This is extremely enlightening. I can't believe it took me until Neuro to finally watch this (already took Histo, Physio, and Biochem and no professor could make this clear for me).
Am medical student from Somalia
And this video and all ur videos helped me alot. am very grateful for u, thanks Dr ninja.
Keep going
Never heard a better teaching tutorial - fantastic, crystal clear or as we call in Urdu "Sheesha"
Hehe
Possibly the best video out there that explain vision physiology and phototransduction in particular. Very thorough and virtually a whole chapter in a video. More power!
Amazed at his fluency and knowledge on Transduction cascading..
As an optometry student, we thank you GREATLY. Incredible, in depth, yet precise. Thank you so so much for this!
you always save me before every single exam- thank you so much for all the effort you are putting into your lectures!!!

You are a well “versed” educator, and incorporate a lot of really useful techniques to make the information absorb easy peasy!

Thank you so much, watching your neurology series, and they’re really helpful.
thank u baby
Thanks

I really enjoyed your joke about the cells not being bi-polar
Which cells???
This is the by far the best explanatin I found in the web for phototrunsduction, it is all so much clear now and I thank you for that!!!
Thank you for this video! You speak so clearly that I can speed it up and go over the video again quicker as a review.
From the bottom of my heart, God bless you! Thank you for helping me understand what I've been trying to make sense of throughout a whole semester at optometry school lol this and other videos. All your videos from ALL the subjects ROCK!
I'm a psychology student and I watch your videos.Because you cover everything and explain it so well that I can understand it easily.Thank you.
honestly dude you are the best teacher ever. these videos are a game changer.
I hope you know how much we all love and appreacite everything that you do. You truly are the ost amazing person on the planet
So grateful for these videos, especially as a visual learner. Thank you so much! Imma buy me some gear!
Hey professor

thank you for saving my life in midterm season. this is a great contribution to youtube!
My professor is not interacting with our online class so these videos are so helpful to me. Thank you for taking the time to explain things in detail. You really make it easy to follow. Great job!
Couldn't ask for more... you're the reason why I'll pass my exams... thanks to the moon and back
You are the only reason I am surviving my neuroscience class right now. Thank you so so so much!!
i am addicted to ur way of teaching complicated topics,hats off sir
Hello!
This is awesome!
I am a second year medical student, and this just made my day! Thank you :)
I’m so a ninja nerd. God bless u for gift in teaching. That made so much sense. Thank you
The way you make the things simplier is just awesome . It's really helpful. Thank you so much😊

Your channel is amazing!! Please keep posting. If I wasnt a student and/or had at least some disposable income I'd love to become a patron. But for now, a thank you is all i could do. :)
Im sorry i dont have a job to donate but i honestly can't believe that GOLD like this is free of cost for students to access.
Thankyou.
Amazing presentation, Mr. Ninja. I have watched many of your videos to better understand the materials I'm learning in school. Your presentation and mastery of the subject matter is far above any professor I've had. Thank you!
I love your videos...I am almost to become opthalmology specialist and am studing for final exam, I find your videos easier to study than my books.
Mate this is brilliant. Im a past bioMed student and recently found the urge to learn about vision in newborn. This has been a fantastic refresher course to help me remember the basics. More people need to be doing this kind of stuff.
Youve got a new subscriber 🎉
And not on the basics to downplay this lecture. Concise and informative. Well done
i want to cry and thankyou and i just want to personally meet you just to say that your efforts and hardwork really matters to us ..thankyou . thankyou so much
i love it!!!
I dont even understand how 40 minutes pass.
your videos are insanely useful and informative, and easy enough to follow. Thanks and never stop teaching.
This was extremely helpful... i can finally understand this process thanks to you .. u simplified it so well thank u so much ... i can't believe this is available for free ❤
Preparing for my resident exams,your video sir has been really helpful
how could it be this perfect
Thanks so much for the fantastic quality of the contents. You educate better than instructors both in Iran and the US. ❤
The way on which you are giving the lecture i am speechless about that sir❤
I have an exam in 5 hours and this man single handedly helped me pass neurosciences
All your videos are outstanding, filled with plenty of information, easy to understand and retain for a longer duration of time... I wish I could get a common like button to hit all at once.. I have not come across even a single that I did not like or could skip watching. Great work done!! Please keep doing what you are doing... Your work is exceptional.

Thank u and continue in your good work..
God bless u
Thank you so much, i am a year one Optometry student and this video covered basically most of my content
"PhoTOtranSducTioN" is a lot i can't belive you drew the whole thing out!! Mashallah brother 🔥🔥🔥
Simply wow! Great! Love from India 🙏✨🇮🇳🌹

Is it just me who watched this video on its entire 42 mins without a break or is there anyone out there
I watched it at ×2 so i guess its 22 min then
😊😊😊😊😊😊

I am just so happy watching this. This makes the topic seem less tough and more understandable
This is my favorite youtube channel
Your videos are way more helpful than my physiology professor.
I think this man took that Limitless pill! Wow THANK YOU
Here 6 years after and this is still the best!
You sir deserve a medal for this. Like you, I finished the video with a "holy crap" too. but thank you!
You deserve 1M more subscribers!!! Your content is invaluable and helped me so much thru uni :)))
thank you Professor Zach, because of this video I passed the exam :D
May be you aren't aware but indirectly you are working for a good cause thank you ninja nerds you are my saver
You’ve outdone yourself once again!!!
amazing video. your video is really understandable. I am an optometrist student and I watch your all ophthalmic related videos. Each video is so nice keep it up sir
Incredible video. Thank you, sir! Your excitement makes the video be fun to watch. You da man!
I wish I could take ur lectures sitting in front of u... Anyhow... This too is a blessing ☺️... Even for a very minor topic ,, I junmp to ur videos.. as my concept is 100 percent clear after watching the video🌸
Thank you for saving me in Optometry school!!
If i pass physiology it's only thanks to this guy
I'm studying photoreceptors for an assignment at uni and this has been a really informative and engaging video. Thanks loads.
Just watched this as I was curious as to what happens to a photon in the eye, not a medical student, still understood it. Good work
you really make the locdown productive,love you loads
U r a saviour....lots of love from India ❤️
Ninja Nerd Online University (With Professor Murphy!)
-- A blessing to humanity
Thanks for being there for us .
Very thankful for the great work of the whole team
thanks a load for decorticating complex content into easily grasped info
Excellent presentation and accurate explanation.
The recap is the best thing ever 😊
I love your lectures! There are no analog systems in the body. Our brains are massively parallel biologically driven digital processors! Our 5 senses are peripheral systems feeding into it. In your Special Senses lecture you illustrated the wiring diagram of the focus and iris servo feedback loops which are critically damped. I love your series!!!
Amazing video!!! This has been incredible and allows me to understand fully the content!!! Thank you all.
So gifted
May God reward you
Very informative ❤
You are the god of all doctors
You are amazing
Thank you for amazing explanation you are better than our professor in my university ❄️🌸
This was by FAR the best explanation of phototransduction; comprehensively reviewing this entire segment from my neurology class nearly 2 years ago. I can't thank you enough for taking the time to make, edit, and post this video!
~That was amazing to watch this young man explain the complexities of the human eye.🙂
I would not be able to survive dental school if it wasn't for you. Thank you soo much!!! I am a hugeee fan!
