Target-enriched functional response during the emotional face-matching task
For the tb-fMRI analysis, the dominant BOLD time series of the target-enriched functional systems were estimated at the subject level as described previously. In the second step, the resulting subject-specific time series were used to estimate the 5-HTT- and 5-HT1AR-enriched faces > shapes functional response using a generalized psychological–physiological interaction design with five regressors, namely the convolved faces > shapes regressor, combining both
