"Transient restricted diffusion in the ipsilateral striatum and/or thalamus is sometimes seen following frontal lobe surgery. The transient restricted diffusion first manifests between 1-3 weeks following surgery and resolves beyond this time point 4."
"There are three main inputs to the striatum: the cortex, the thalamus, and the brainstem (primarily from brainstem dopaminergic cells). The striatum in turn projects to the pallidal complex and the substantia nigra 1."
