This Research synthesizes current research on the neural circuitry of emotional regulation, focusing on evidence derived from multimodal imaging studies. We provide a comprehensive overview of the key brain regions and neurochemical pathways implicated in emotional regulation, as elucidated by functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and electroencephalography (EEG). Our analysis highlights the central roles of the prefrontal cortex, amygdala, hippocampus, and anterior cingulate cortex in modulating emotional responses, while also emphasizing the dynamic interplay between these regions. Findings from fMRI studies underscore the involvement of cognitive reappraisal strategies mediated by the prefrontal cortex, while PET studies reveal the neurochemical underpinnings of emotional regulation, including serotonin and dopamine systems. EEG studies provide insights into the temporal dynamics of brain activity during emotional processing, elucidating the rapid interplay between cortical and subcortical structures. Despite significant advancements, limitations such as study design constraints and sample size limitations underscore the need for continued research efforts. Future research directions include advancements in imaging technology, longitudinal studies, and exploration of individual differences in emotional regulation. By addressing these research priorities, we can deepen our understanding of emotional regulation and its implications for mental health, ultimately informing more targeted and effective interventions for individuals with emotional disorders.
