Emotional resilience—the capacity to adapt effectively in the face of adversity—is a critical factor in mental health outcomes. With advancements in neuroscience, researchers have begun to identify the specific neural circuits and mechanisms that underpin resilient behavior. This narrative review synthesizes recent neuroscientific literature on brain-based correlates of emotional resilience, highlighting the role of key regions such as the prefrontal cortex, amygdala, hippocampus, and anterior cingulate cortex. We explore how these regions interact to regulate stress responses, emotional processing, and cognitive control. The review also examines the impact of evidence-based interventions including cognitive behavioral therapy (CBT), mindfulness-based stress reduction (MBSR), neurofeedback, and neuromodulation techniques (e.g., transcranial magnetic stimulation) in enhancing resilience through neural plasticity. Functional neuroimaging studies demonstrate that these interventions induce measurable changes in brain activity and connectivity, promoting adaptive coping strategies and emotional regulation. Furthermore, we discuss pharmacological approaches that target neurobiological substrates linked to resilience, particularly in mood and anxiety disorders. Limitations of current research are acknowledged, including methodological variability and the need for longitudinal, culturally diverse studies. This review underscores the value of integrating neuroscientific insights into therapeutic models and encourages continued interdisciplinary collaboration to optimize interventions for mental health resilience.
