Figure 1 Integrated schematic model of electrophysiological alterations in emotional and reward processing in major depressive disorder and potential intervention targets. The figure summarizes key event-related potential components involved in emotional and reward processing, their associated neural circuits, underlying molecular and cellular mechanisms, and potential intervention targets. MDD: Major depressive disorder; ERP: Event-related potential; LPP: Late positive potential; SPN: Stimulus-preceding negativity; CNV: Contingent negative variation; RewP: Reward positivity; FRN: Feedback-related negativity; PFC: Prefrontal cortex; ACC: Anterior cingulate cortex; NAc: Nucleus accumbens; VTA: Ventral tegmental area; LHb: Lateral habenula; 5-HT: 5-Hydroxytryptamine; GABAergic: Gamma-aminobutyric acidergic; Glu: Glutamate; GABA: Gamma-aminobutyric acid; BDNF: Brain-derived neurotrophic factor; CB1R: Cannabinoid receptor 1; CBT: Cognitive-behavioral therapy; tDCS: Transcranial direct current stimulation; rTMS: Repetitive transcranial magnetic stimulation; SSRIs: Selective serotonin reuptake inhibitors; SNRIs: Serotonin-norepinephrine reuptake inhibitors; DBS: Deep brain stimulation.
