Article Figures & Data
Figures
- Fig 1.
Structural images showing voxel localized in the frontal lobe on the midline above the genu of the corpus callosum, to include the anterior cingulate cortex.
- Fig 2.
GABA+- and GSH-edited spectra from participants with a fit error of <15%. GABA+-edited spectra are acquired using both HERMES and MEGA-PRESS sequences.
- Fig 3.
GABA+ and GSH correlations with age. Significant correlations are observed between GABA+ and age, whereas GSH does not significantly correlate with age. r indicates the Pearson correlation coefficient.
