Abstract While the hyper-and hypo-reward or punishment sensitivities (RS, PS) have received considerable attention as prominent transdiagnostic features of psychopathology, lack an overarching neurobiological characterization currently limits their early identifications and neuromodulations. Here we combined microarray data from Allen Human Brain Atlas with a multimodal fMRI approach to uncover signatures RS PS in discovery-replication design (N=655 participants). Both were mapped separately brain, intrinsic functional connectome fronto-striatal network encoding reward responsiveness, while fronto-insular system was particularly engaged sensitivity. This dissociable patterns related also specific differentiating decisions driven by social monetary motivations. Further imaging transcriptomic analyses revealed that variations for associated topography gene sets enriched ontological pathways, including synaptic transmission, dopaminergic metabolism, immune response stress adaptation. On neurotransmitter level, serotonin neuromodulator identified pivotal hub regulating PS, this process critically dependent on its interactions dopaminergic, opioid GABAergic systems. Overall, these findings indicate neural mapping highlight linkage profiles, which may offer valuable insights into treatment evaluation symptomatology relevant reward/punishment processing deficits.
