Correlating functional connectivity with occipito-temporal cortex (OCT) γ-aminobutyric acid (GABA)/tCr change. a Skipped Pearson’s correlations showing a significant positive correlation of OCT-posterior parietal cortex (PPC) connectivity with OCT GABA/tCr change for the feature differences task (n = 19, r = 0.55, CI = [0.13, 0.87]), but not the signal-in-noise task (n = 16, r = 0.27, CI = [−0.08, 0.60]). We computed GABA/tCr change for each participant as the difference between GABA/tCr in the training block with maximum performance and GABA/tCr in the baseline block. b Skipped Pearson’s correlations showing a significant negative correlation of functional connectivity within the occipito-temporal cortex with OCT GABA/tCr change for the signal-in-noise task (n = 16, r = −0.55, CI = [−0.86, −0.01]), but not the feature differences task (n = 19, r = 0.12, CI = [−0.29, 0.51]). Significant correlations are indicated by closed symbols; nonsignificant correlations by open symbols
