- Basal Ganglia and Dopaminergic Pathways for the USMLE Step 1. Master the dorsal striatum, lentiform, putamen, globus pallidus, substantia nigra, subthalamic nucleus, ventral tegmental area, and the nucleus accumbens. Dominate the nigrostriatal pathway, mesolimbic pathway, mesocortical pathway, and the tuberoinfundibular pathway. Plus, know the difference between D1 and D2 receptor stimulation.
Neurology is a beast, but we've worked hard to tame it a little bit for you.

Mad respect to you guys for putting quality content out there for free!
I've watched so many videos but no one could explain this better than you did. I can;t thank you enough.👏👏👏
This was so amazing, explained so simply, yet had all the detail I needed to understand. thank you so much
🙌❤ We're glad you like it!
The explanation of the dopaminergic pathways at the end was super helpful! haven't found any other video resource which explains those
Finally understood the topic after being confused by every other video.
There is alot of videos discussing basal ganglia, but this one is a gem. Thank you so much, this is very useful!
I m an italian student of Medicine and thank u very much this was really useful!
Amazing.thank you very much for the explanations.You made it very clear and easy for me.I was reading and reading trying to figure out how to understand the basal ganglia.
Thank you for your time & effort; great post
Clear cut idea in short time.
Covered what I wanted.
This video is amazing! Thank you so much for very clear explanation of pathways 😀
Thank you so much. I just reat it several times and watched some other videos too. But didn't get anything. This video really helped me 😊😊😊
Amazing video and great explanation methods, thanks alot !
OMG love youu thank you so much !!! I read for hours didn't understand anything in just 20 mins you enlightened me :D
Extremely thorough! Thank you!
Wow ! Nice explanation
Highest level respect...
you make it looks simple great work .
Huge thanks!
Thank you
This was amazing. Thank you so so much! I have one question and that's which Dopamine receptor sub types that are stimulated in the 4 pathways? You mentioned only the nigrostriatal pathway. I couln't really tell from my book. And some other video here on youtube mentions it's D2 on them all?
That's reason of lack of inhibition 😊🙏❤️
Can't believe this is free!
Amazing Explanation!
I was under the impression that cerebelum was responsible (besides other things) for precise VOLUNTARY motion, such as the ones involved in playing fast passages on the piano, and that the basal ganglia was involved in modulating mainly INVOLUNTARY motion, such as the feet taping reflex when we entrain to a external regular rhythmic periodic pattern (music that has pulse).
Now Im confused. Can anyone help? Im just starting with this
Hi, thank you so mcuh for these videos! I've just signed up for an account with Physeo. Can I ask though, is the nucleus accumbens not part of the basal ganglia? Then reading further, it says it can be considered both> Is this just a grey area? (pardon the pun)
Thank you so much .It is very clear and enough information for me.Can you add more videos relative to usmle exam
We absolutely will!
Really appreciate
Thank you so much for your effort, but i have a question please . Isn't it supposed that the SNc send the first excitatory impulse to the striatum not from the motor cortex in the direct pathway?
Great explanation... thanks you
this is amazing. which book are you referring to for diagrams. please help
Hey! All of the images are from our textbooks. You can get access to all of them by visiting www.physeo.com and signing up for an account
Thank you so much. Which book are you referring to?
Nice and good explanation
Thank u ! Really helpful
im gonna kill that online test on monday thanks to you!
Did you? (I hope you did)
So does this pathway also affects speach and singing, since those are smooth voluntary movements?
Thanx i was so confused
We're glad this cleared things up! 😎
Why are there no videos about the role and pathways of basal ganglia in psychiatry?
petra shusek.....there is a channel called "Dirty Medicine" that addresses the Dopaminergic pathways. Here's the video.

Ultimate
This is amazing
Seems like the dopaminergic pathways are ultra-important.
Sir, from which textbook you are teaching ?
gold!
Omg thank u so much!
Thanks for watching! We're really glad you like it
why do the same glutamic stimulation of caudate and putamen result in different actions >
gold
Might have missed this but whats the purpose of activating the caudate?
Which book you referr for study purpose?
How dopaminergic pathways affect movement intensity.
Neil Lamas.....Maybe this video will help.

can we say that we have 2 pathways.first is direct pathway which facilitates motion and we have indirect pathway which inhibts movement.and then (this is the part where i am confused) we have bunch of dopamine on our hands.when we add these dopamines to direct pathway it increases movement,but when we add these dopamines to inderect pathway it inhibits the indirect pathway so we increase motion(movement).help........
You're absolutely right Tural. That's exactly how it is.
Yes you are right dopamine inhibits D2 so D2 inhibits more motion is occur
