Caudate, putamen, globus pallidus, or subthalamic nucleus - usually asymptomatic but may cause hemiballismus. This is called the basal ganglia lacune. possible vessels involved during stroke that causes this syndrome: lenticulostriate (from MCA), anterior choroidal (from ICA), thalamoperforator (from PCA) or Heubner's arteries (from ACA).
Thank you for posting this. It is a very sad condition, indeed, but your post has made it so that I will never forget what it looks like to have hemiballismus.
@humtoharhou STN. Wouldn't a lesion in the striatum (putamen + caudate) also inactivate the direct pathway, leading to decreased movement (countering the increased input to the thalamus from the indirect pathway, post-STN lesion)? I thought it was just STN in hemiballismus.
@dska22 What you wrote is my understanding as well...unless humtoharhou was thinking of a more subtle lesion of the striatum, like the loss of medium spiny neurons that you see in Huntington's disease. But, yeah, total loss of the striatum (like a stroke) would give you parkinson type symptoms, not hemiballismus or chorea.
I think I have something similar to this. But in my hand and forearm, i just slighty flex my forearm and wrist muscles, it makes it so i can not type with my left hand
is this DRPLA?

I'm just learning neuroanatomy, but these videos are very informative about what happens when something in that or that nucleus goes wrong :)

it's because of a lesion in the subthalmic nuclei

I wonder if the patient gave her consent, that the video is now published here.
