That is, for each participant, GSH levels were estimated after correcting for partial volume effects in each voxel using the method proposed in Gasparovic et al(Gasparovic et al., 2018), and GABA levels were alpha-corrected(Harris et al., 2015), since metabolite levels are reported to differ between brain gray and white matter(Gong et al., 2022)
