Relationship between SSRT, locus coeruleus and drug. (A) SSRT estimates as a function of drug condition and locus coeruleus CNR. Within-subject change in SSRT from placebo to atomoxetine is illustrated with vertical grey arrows. (B) Relationship between locus coeruleus CNR and the drug-induced change in SSRT. For visualization purposes, the SSRT estimates were adjusted for the fixed effect of session and random effect of participants (i.e. partial residuals).
