From: GABA concentrations in the anterior temporal lobe predict human semantic processing
Results of the Brain Imaging Analysis: (a) The fMRI BOLD signal associated with a semantic task (semantic > control, thresholded at p FWE-corrected < 0.05, ks > 100). The green box represents the MRS volume of interest in the left anterior temporal lobe. (b) A representative MR Spectrum in the ATL with estimated peaks including Glx (a composite measure of glutamate and glutamine), GABA and NAA (N-acetylaspartate). (c) Scatterplot showing the negative correlation between individual GABA/NAA ratios and fMRI BOLD signal changes in the ATL. (d) Scatterplot showing the positive correlation between individual GABA concentrations and semantic task performance.
