Ascending Tracts | Pain Modulation: Gate Control Theory 

This channel is a BLESSING. I might just cry a little.

I'm a medical student studying for my medical boards exams and this video series is one of the best I have ever seen on RU-vid. Thank you so much for all of your hard work!

What's your name, dude? I'd like to address you by name when I include you and your videos in my evening prayer thanking God for all the things that spice up my life 👏👏👏

I've been trying to understand this for the last 24h and you just made it simple in the last 24 minutes. YOU'RE AMAZING MAN!!!!!

Thank you so much. Even your enthusiasm is contagious in a positive way which makes the topic very interesting.

Gate Control Theory explained by our talented and gorgeous friend Zach 00:00- 12:09 Descending Analgesic Pathway 12;09 onwards Thanks for saving me again xxx

Zach, you are honestly a hero. Thank you for doing this , you don’t know the impact these videos make on those entering the medical field!

I 'm addicted to ur vedios.I wish I had u as my teacher in med school.5/5.

As I continue to watch these videos, over and over again; I continue to become more confident, and I understand neurology a little bit better, and better; and it feels real good. It is a very nice feeling. Thank you for teaching us Zach. Thank you Ninja Nerds.

Your channel is a gift to mankind. Great job! Keep it up!

OMG!!! You made more sense than my lecturer!! very easy to understand with your diagrams and your explanations covered all that I required. Thanks mate!

Thank you for your really great lectures. Genius! The ability to take something so complex and make it so simple!

dude i swear..if your channel doesn't blow up!

Great, great, great!!!! I pay for my studies and none of the teachers can explain it the way you do! Thanks a lot!

I cannot even start to express how much this has helped me get a better grip on pain physiology, opioid physiology and general neuroanatomy!!!! This video is amazing.

Your videos are class, I'm a third year physio student and you make everything so interesting to learn. Thank you.

thank you so much for bringing these detailled lectures to students all over the world

You, sir, are the MVP! You explain so well and so many of us can sense your passion for the topics that you are lecturing about and also in a very pedagogical way. Thank you so much! From a physiotherapy student

Fantastic! Great video with clear and concise explanations - would love to see one on central and peripheral sensitization as well!

Amazing. Thanks for all your work. Best description I have found yet.

I wish we had teachers like you in Indian med schools. Hardly anyone here is even interested in teaching, all they are concerned with is completing the curriculum and taking examinations. You're so enthusiastic about the topics you convey.

You are the very reason why I am liking neurology now, cannot thank you enough.

That was very useful and informative. It was difficult to read the text with all the really weird and confusing name, but managed to put it in simple terms. Thank You and keep up the good work

I honestly never watch videos for learning because it's hard to understand, but Ninja Nerd makes it easy to understand. THANK YOU SO MUCH!

I'm spanish speaker, and it's quite difficult to find good work like this in my native language. I've found your videos not so long ago and I swear, they are PURE GOLD. Thnk u so much for your hardwork and dedication.

I rarely comment videos on youtube but this time I do this because your job is highly amazing. Thanks so much. I read up to hundreds book of physiology but I did not understood these pain modulation theories until I watched your video. It is really a great job. I even watched plenty of youtube video about pain physiology but none of those video explains with much clearness and precision than your video. May the Lord send on you a storm of his graces and gifts. Once more, thanks a lot.

Your the first person who made me understand gate control. Thank you!!

Completely amazing videos. I'd be completely lost without your awesome drawings. Thanks so much for the work, I'll surely donate to your gofundme.

Exceptional Zach, thank you for your hard work 🙏🏻

This is utterly phenomenal. Thanks!

I love your videos! You were born to teach and we are THANKFUL for it :)

Great video man! I went to a meditation retreat one and a half years ago where I had to meditate 10 hours a day for 10 days. About a fifth day in I felt intense pain in my back but the instructions were to just accept the pain and not to react and wait for the pain to pass. So I was about 45 minutes in to a 1h session and I was really on the verge of giving up and ready to move my body to relieve the intense pain, when all of a sudden I felt the intense pain just evaporate. Instead I felt this pleasent buzzing numbness. And the funny thing is it became a habitual response for my body so the next time I felt that intense of a pain in my back I didn't even have to suffer for 45 minutes before my body decided to relieve the pain. You helped me undestand some of the mechanisms that were behind my experience and I am sincerely grateful for that!

Dude, this is freaking epic. Thank you so so much

Such a great video! Thank you so much for all of your effort.
