What regions of the brain do the medial striates supply?
ALIC, caudate
What deficits do you see if medial striates are occluded?
Frontal ataxia (Burns ataxia)-lesion in fronto pontine produes difficulty in intiating movements such as walking, although strength and coordination are normal
What regions of the brain do the lateral striates supply?
