The false positive (FP), false negative (FN) and retained (R) BOLD activity were identified by comparing the sensitized group results to that from standard BOLD analysis. The “+” and “−” sign denoted the BOLD activation and deactivation with respect to resting BOLD activity; L- and R- prefixes denotes left and right hemisphere brain area; Y, young; O, old; SFG, superior frontal gyrus; pre-SMA, anterior supplementary motor area; PCC, posterior cingulate area; PCUN, precuneus; Ling, lingual gyrus; V1, primary visual cortex; mPFC, medial pre-frontal cortex; AG, angular gyrus; PMd, dorsal pre-motor cortex; Pop, pars opercularis; M1, primary motor cortex; STG, superior temporal gyrus; postCent, post-central gyrus; MOG, middle occipital gyrus; IPL, inferior parietal lobe; MTG, middle temporal gyrus.
