We report measurements of GABA concentration in infants without sedation using the MEshcher-Garwood (MEGA) sequence. Single-voxel measurements were performed in 114 infants at approximately one month and/or three months of age. Quantification is performed with water scaling, and concentration values are reported in units of mM of NMR-visible water in the brain. For the two scan times, we found the inter-subject coefficient of variation (CV) of GABA to be 8% and 9%, respectively. Average GABA concentration values are 7% higher for the 3 month scan than the 1 month scan, indicating a gradual increase in GABA concentration after birth.
