Multi-echo GRE was used to visualise
BOLD signal changes in the midbrain, specifically targetting the subthalamic nucleus and substantia
nigra, with submillimeter resolution. Midbrain
clusters were very small and often only bordered the STN or SN, rather than falling
robustly inside it, emphasizing the need for high spatial resolution.
