You are a blessing for every medical student. Love and respect you from the core of my heart. I dont know how to express what I am feeling right now. Just.. Be billionaire and stay in good health.
You are a life saver... we have an Anatomy teacher that basically disappeared and abandoned her students and I have been able to provide them content through your videos. THEY LOVE YOU! Thank you!/
I love this video, and I am excited to watch the rest of the cranial nerves - which I know far less about. I've been working in an ENT department for about 1.5 years now, so I wanted to add a few things. First: anosmia is complete loss of smell, hyposmia is reduced smell. Usually, during a cold, you have hyposmia. The most common causes in order of anosmia are as followes: 1) Post-viral injury/damage 2) Trauma breaking the nerves 3) Chronic inflammation, like from allergies, covering the olfactory nerve 4) Far less common, tumors or masses. Also, one thing awesome, if the nerve is damaged from trauma or an infection, the olfactory nerve is the only cranial nerve that can grow back, so the doctors I work with are know recommending olfactory retraining, sort of like PT for the nose. It has worked pretty well.
wow, my university made us just remember the lesions from 5-8 blindly without any explanation. You have made everything clear, cannot thank you enough! 🙏🏻 , please keep up this channel! 👌🏻
trust me ive watched several videos about visual pathway and lesions but yours is the best i couldn't understand till i watched yours THANK YOU SO MUCH you are saving a lot of peolple here ! God bless you
I'm an international student in Germany, majoring in biology (well not a medical student). German is not my first language and i feel like I always need more time to understand what was taught in the lecture than other fellow students who are germans. I'm currently taking Physiology as a module this semester and I just can't stress it enough..how grateful I am to have found your channel 🥲thank you so much!!
I'm blown away by your ability to unpack and communicate such a potentially intractable subject (bad pun). Your choices of when to use "Nasal/temporal" vs "L/R" were astute, and kept left/right confusion to an absolute minimum. You have helped a lot of people with these videos. THANKS!
U r a brilliant genius teacher....this video suddenly gave me the energy to study hard nd understand the basics....u r soo awesome...loved ur way of teaching...thank u soo much Sir😇💙
I learnt the visual pathway in my first profession and now I'm in an internship and wanted to revise, use many other videos but still your lecture made it simple and clear all my doubts as clear as it was in my first profession.
This is so freakin brilliant! Heard this so many times from so many people, this is the first time ever that I actually grasp the whole thing. Thank you so much!
Oh my God! What an explanation! i UNDERSTOOD THE conecpts vry clear..Thank U so much Sir U make medical Students life easier! Keep making more Videos Sir
I actually fucking love you, thank you so much. You thoroughly yet concisely explain everything perfectly and I completely get it now. This deserves wayyyyy more than 5k views
this is excellent. i have Left homonymous hemianopia due to a hemorrhagic stroke because due to a ruptured PCOM artery ...i had endovascular coiling surgery with stent. i developed hydrocephalus hemorrhagic transformation among other complications. october 2022 will be one year/
The only criticism I have for this video is that the lesions along the Meyer's Loop & Baum's Loop should be referred to as a quadrantonopia (not a hemianopia, as hemianopia refers to blindness in half of the field)
Absolutely brilliant! I had a major stroke 18 months ago which left me with left inferotemporal quadrantanopia and this is the irst time I have really understood what the real cause actually was and what had been damaged Thanks so much
Really, Well done!! This one of the best videos I've ever watched at my whole studying experience!!👏👏👏 I learnt something after a hundred of repetition OMG! Thank you so much 🙂🙂✌️💪💪
You guys are the single best medical content lecturers out there! I am wishing you guys all the luck of this world in your future endeavors! Greeting from Greece!
I was never able to those lesions posterior to the optic tract. It was always a frustrating point. Thaank you sooooooo much for finally clearing it up! Feels amazing to know I finally understand it :-))))
THE NINETY DISLIKES ARE ALL SALTY MED SCHOOL PROFESSORS WHO SPEND 7+ HRS FAILING TO EXPLAIN WHAT NINJA NERD EXPLAINED IN LESS THAN 40 MINUTES . you sir, are the 8th world wonder
The afferent fibers for light reflex leave the optic tract just immediately before the tract gets in to medial geniculate body. Then these afferent fibers go to both the ipsilateral and contralateral pretectal nucleus of mid brain. This is an important anatomical explanation for the consensual light reflex occurring in the opposite pupil. Thank you
Hi, I reallyyyyy love your videos. I think you are so clear and effective at explaining concepts that the professors at my university struggle to express to students. Especially since I have been online this semester, your videos have been a crucial part to my education. Would you consider in the beginning of your videos allowing for the screen with all the blank templates you drew out prior to starting the video to be recorded just a few seconds without you in frame so, we can screenshot and follow along with you as you draw it out? Thank you so much!
I have no words to express how grateful I feel that I found you guys, thank you for the immaculate and full of love job YOU ARE MAKING A DIFFERENCE for all med students struggling around the world 🌍💓
Your videos are amazing!!! They're helping me a lot!!! Right now I'm going to each video you made about the cranial nerves, because my upcoming exam is soon. Your explanations are very good and understandable and your drawings are also perfect! Thank you very much for your nice explanations, pictures, efforts, etc. I really appreciate your emphasizing methods through many repeated sentences and that you sometimes shortly! go back to already discussed structures. I'm enjoying watching your videos and learning a lot :)
Purple💜💜💜, I like the way how you play ć colours, I just now ordered a purple tab from Amazon, and hearing purple out of your mouth, put a big smile on my face . 😊
can't even fathom how much time did you took to make this complicated concept this simple!!!!! great teaching communication !!! awesome!! kudos mate :)
Excellent teaching sir...I am a 1st yr MBBS student in West Bengal in India ....I read the visual pathway from book but was unable to understand 60% ...then I watched ur video ..now I think my concept is pretty clear....
oh boy.. this is just the optic nerve.. wonder what the glossopharyngeal nerve is going to be like! An old neurobiologist told me one time that we have 12 cranial nerves and it takes a minimum of 12 years to learn them all. That statement is correct!
I wish my lecturer was this informative and good. She just comes to the lecture and changes slides. A new lecturer arrived yesterday, he was decent but still not this good.
@NinjaNerdScience your videos are absolutely quality. I learn more from you, then lectures at med school. Thank you so much your intelligence and quality of teaching is phenomenal.
Personally I think you should've stuck to nasal and temporal. I appreciate your intent behind it but I think that students should get used to nasal and temporal ASAP, no matter how confusing they may be, because that's how it will be known anywhere else. Also, the left VF of the left eye may be even more confusing in future since it's 'left of left', 'right of left' etc.
Furthermore when you say 'right VF goes to left' etc., can also be confusing again. Think it would be better to say temporal stay, nasal cross or something equivalent.
Really love your presentation. There are a few mistakes though. Quadrantic field defects are known as "quadrantanopia" and not 'quadrant - hemianopia'. Hemi means half.
I am studying physiology...and this semester my chapter is special sense....n i find ur video n for every topic i search from ur video it really help me a lot .....❣️BEST VIDEO
I feel so dumb.. For past 6 years I had wrong understanding of visual field tract.. Left to right and right to left.. You made it so easier .. I was missing this basic concept.. Thanks a lot.
YOU COULD SINGLE-HANDEDLY PUT ALL THE PROFESSORS IN MY MED SCHOOL TO SHAME
I think half of the world's med school 😅😂
Yea, mine too 😂
seriously.. 95% of them suck at explaining and delivering the concepts while the remaining 5% hardly ever get assigned to my group..
well yeah he probably gets paid more than them
@@rafiyashaikh2368 the whole world's med schools actually😂
You are a blessing for every medical student. Love and respect you from the core of my heart. I dont know how to express what I am feeling right now. Just.. Be billionaire and stay in good health.
Just wow😮 Five(5) years later and still unmatched Crystal clear concepts 🙏
I would never get this information from my university, you made everything crystal clear THANK you so much ..
Where r u frm friend our colges are same too yaar
he probably gets paid more than university instructors
Which country

john towers, yep! I was watching the olfactory video. Somehow I commented on this one, but I’m not erasing it.
Thanks. Interesting 👌

I am neurology resident and you are my official reference for neuroanatomy, this is unbelievable you are a legend
so do I and I agree with you.
trust me ive watched several videos about visual pathway and lesions but yours is the best i couldn't understand till i watched yours THANK YOU SO MUCH you are saving a lot of peolple here ! God bless you
Every single video of yours is awesome.. First year med student here..and for me you're nothing less than a blessing..

I am enjoying learning Anatomy with Ninja nerd .what a joy I found you.
Hi Same here. I’m learning anatomy in my fourth language, French. Thankfully, both French and English share a lot of terminology in common.
I literally cheered because i finally understood how the various lesions impacted on vision. maybe you saved my ophtalmology exam next month!
holly hell.. i cant believe i actually followed through the whole thing .. lol ..ur a gem. THANKYOU
U R A Blessing to medical students
This is excellent work mate! Keep it up!
We plan too! Thanks so much!
There are not enough words to describe how much i appreciate your efforts. THANK YOU
You're doing a great job Zac. 30 minutes and optic tract is clear. Can't thank you enough. Be blessed sir!

All of your videos are soo helpfull. I dont even have to pick up my book. Thank youu. This all means alot.
I was never able to those lesions posterior to the optic tract. It was always a frustrating point.
Thaank you sooooooo much for finally clearing it up! Feels amazing to know I finally understand it :-))))
never knew neurology could be this fun when u actually got a good teacher, thanks alot
though i cannot pay them through direct funding but i watched twice ads not skipping it so that i might help the team thanks alot
i think clicking on the ads helps them too
They have a Patreon that you can contribute to! I just give a dollar a month since that's all I can do for now
Man it's amazing how you cover up everything necessary for the each topic. You are doing a holy job thank you so much !!
Amazing work...God bless you sir.Love from Pakistan
I'm not a doctor or plan to be but I stayed at a Holiday Inn Express. I really enjoy your explanations. No anxiety when I don't have to memorize.

This is timeless content - always find myself coming back when i need some refreshing
Your videos are amazing!!!
They're helping me a lot!!!
Right now I'm going to each video you made about the cranial nerves, because my upcoming exam is soon.
Your explanations are very good and understandable and your drawings are also perfect!
Thank you very much for your nice explanations, pictures, efforts, etc.
I really appreciate your emphasizing methods through many repeated sentences and that you sometimes shortly! go back to already discussed structures.
I'm enjoying watching your videos and learning a lot :)
Thank you! This is amazing I really appreciate this effort, you made everything crystal clear.
i cant tell you how thankful and grateful I am.
Sir you are the best ever, please complete autonomic nervous system and many topics in embryology thanks, you are highly awesome
Thank you, we will have the sympathetic and parasympathetic videos up by mid December. 👍
Purple💜💜💜, I like the way how you play ć colours, I just now ordered a purple tab from Amazon, and hearing purple out of your mouth, put a big smile on my face . 😊
your vast knowledge blows me away...when did you first start studying all this?
can't even fathom how much time did you took to make this complicated concept this simple!!!!!
great teaching communication !!! awesome!! kudos mate :)
Holy Sweet Goodness! Just learnt a lot from this. Recommended by a friend. Thanks bro.
No words........ 🙏I think i don't want to revise or study this again cause yr the master of medicine🔥
You are so awesome! Pls do make a video regarding spinal cord lesions. Thanks much!
All Sudanese Medical Students appreciate and respect your effort ;I know that NENJA NERD represent the whole world.
Thanks so much! This was very helpful in my review of the visual pathway and VF defects!
These videos are really long, BUT THE DETAILS ARE LIFE SAVING
My brain cells gave up on lesion 5 and left my brain completely at lesion 7 😭😩
Excellent teaching sir...I am a 1st yr MBBS student in West Bengal in India ....I read the visual pathway from book but was unable to understand 60% ...then I watched ur video ..now I think my concept is pretty clear....

Such a indigestible topic
Still such flawlessly explained
I am here just to appreciate his efforts. His explanation is far far better than my university professors :)

I need to learn that in 4 days for my exam... Just love time pressure.
I really got Cristal clear clarity on lesions
I'm justing trying to understand these lesions but u can't
But know I can 😀😀
Thank you sooo much
Hi
you are my optic nerve
😂😂 good vision
You made everything so much easier!!!! Thank you
I wish my lecturer was this informative and good. She just comes to the lecture and changes slides. A new lecturer arrived yesterday, he was decent but still not this good.
Damn!!!!! The finest explanation of visual pathway on the internet. Thank you so much man......Great content. Keep it up.
"Turn me over and tickle me twisted" lmfao
Some of his remarks really make me crack up too XDD
Hi
I know explaining a joke makes it lame but I'm really curious to understand
Would you please explain ?
😂😂😂😂crying !!!
thanks 1000times is not enough..i amfrom BANGLADESH and May God bless u ...pls carry on.
Everything was clear but the lesions were somewhat difficult for me to understand. Otherwise good job . New subbie

"I'm sorry, but that's how it works""😂😂😂💜
Its so much complicated in the book , but you dude made it really crystal clear. Thanks
plz make a video of tracks of spinal cord 😢😢😢
What are you studying
Wow i never understood this before. Great work
Thank you put I think you have mistake in 6 and 5 lesion!!
y
ive noticed that too
perfect. need no other video to understand the visual pathways and associated lesion. thank you
I am studying physiology...and this semester my chapter is special sense....n i find ur video n for every topic i search from ur video it really help me a lot .....❣️BEST VIDEO
