Basal Ganglia: Neuroanatomy Video Lab - Brain Dissections

Structures involved in involuntary movements are shown on models, in animations, and on gross coronal and axial sections. Diagrams show the cortex-to-cortex loop and the nigrostriatal pathway. The direct and indirect pathways are shown. The direct pathway facilitates movement while the indirect pathway inhibits movement on the opposite side of the body. Clinical videos of two diseases, Parkinson’s and Huntington’s, are examples of interruption of the balance between excitation and inhibition in these pathways.

This is 22 of a series of 26 videos to be viewed in the suggested order or intermixed with other curricular materials. The entire series can be accessed here:

Can we all take a moment to appreciate this woman?? Dr. Stensaas you are a gift to humanity!! Thanks a lot for all the time put into making these videos!

[onetwoBias]

I just cannot get over the how great these videos are! They really are among the best educational material for medicine that can be found on YouTube in my humble opinion.

[tamtamayo]

Please tell me this phenomenal woman has won awards. What an incredible mind. Yes, as others have said, tops the list of educational videos on YouTube.

[drsmirshad]

Dr. Stensaas you made our life very clear and easy to understand, by providing us with your unforgettable information, and superb correlative presentation. Be blessed.

[priyapalani]

so far the best video on basal ganglia !!! helped me a lot!

[ambraabate]

Helping doctors to learn deeply this difficult argument, you are helping a huge number of patients.

I'm a brand new neuroscience student and the large colored brain model is the coolest I've ever seen. I spent the last half hour scouring the internet and I can't find anything remotely similar. I'm sure it's a super expensive specialized model lol. Awesome though. Great video too! It's the first one I've been able to find that actually shows the
SN(now I see why they named it) and VTA and explained the pathways so clearly. The basal ganglia is definitely one of my favorite parts of the brain. I'm so excited for neuroanatomy! I can't take it for another year and a half cuz I'm still knee deep in pre-reqs but man I'm going to own this class lol.

A superb lecture with excellent specimens and examples. Thank you

[elisabetpietz]

I found this series of videos during the last week before my neuroanatomy final exam, and I am bummed I didn't find them earlier! Dr. Stensaas integrates the identification of structures on the lab specimens with their functions and clinical applications in a beautiful way. It all makes so much sense the way she teaches it. Thank you so much for sharing your knowledge with us. :)

Dr. Stensaas is so clear. A gifted teacher.

[erikagracer]

the animation was made in 1998. I was born that year and now a medical student. :) Thanks for the video ma'am!

[amnabhatti]

a real teacher teaching with real specimens. thank you.

[dr.othmargil]

This is probably the best video that I've ever seen in my life! It helped me A LOT, Thank you for this beautiful explanation!!!!

[davidjones]

So glad I found this video-I start neuroradiology next week. Found this very detailed and helpful. Thanks so much for sharing your knowledge and understanding of the CNS with the world.

[scottcupp]

Your knowledge of our brain is astounding. So much we've learned about the mysterious processing system in our head. We've only scratched the surface.

[mugetsu]

These videos are the only reason I go on YouTube to be honest

[syedazahra]

Hats off mam... absolutely... u combined all the things the specimens, Pics, the 3d and your explanations... and made it all simple... thanks alot... excellent job

[nikkihuang]

This series is amazing, thank you so much for your wonderful teaching!
