This study used 1H MRS to measure and compare brain GABA and glutamatergic compound (Glx) levels in antipsychotic-nave schizophrenia patients during first-episode psychosis (FEP) and age- and sex-matched healthy control (HC) subjects, and found regional elevations or strong trend-level elevations of both neurotransmitters in the FEP subjects.
