From: Dopamine-induced changes to thalamic GABA concentration in impulsive Parkinson disease patients

Location of the MRS voxels in a thalamic and b motor cortex areas. c Example of the edited spectrum. d Representative fitting of the GABA+ peak at 3 ppm and the Glx peak at 3.75 ppm in the edited spectrum; acquired data are in blue, fit in red, and residual in black.
