Summary
This summary is machine-generated.This study reviews the neural basis of emotional well-being (EWB) using a consensus definition. Findings implicate the left pallidum in task-dependent EWB and the right superior temporal gyrus and insula in task-independent EWB.
Area Of Science
- Neuroscience
- Psychology
- Well-being Research
Background
- Emotional well-being (EWB) is crucial for overall health but lacks a unified definition and consistent understanding of its neural underpinnings.
- Previous systematic reviews on EWB neural correlates show inconsistencies due to varied definitions and methodological limitations.
- A consensus definition of EWB from the NIH EWB Research Network (2023) offers a framework for a more unified investigation.
Purpose Of The Study
- To conduct the first preliminary systematic review and meta-analysis of neural correlates of EWB using a recent consensus definition.
- To differentiate and integrate neural findings from task-dependent and task-independent neuroimaging modalities.
- To establish a preliminary neural framework for EWB to guide future research.
Main Methods
- Systematic review and meta-analysis of studies investigating neural correlates of EWB.
- Utilized a 2023 consensus definition of EWB encompassing five domains: goal pursuit, life satisfaction, positive affect, quality of life, and sense of meaning.
- Separately analyzed task-dependent (task-based fMRI, n=14) and task-independent (resting-state fMRI and structural MRI, n=7 each) neuroimaging modalities.
Main Results
- The left pallidum was identified as a key region for task-dependent EWB, potentially related to reward processing.
- Task-independent EWB findings implicated the right superior temporal gyrus (STG) and insula, suggesting roles in social cognition and interoceptive awareness.
- Frontoparietal regions were consistently identified across both modalities, likely supporting cognitive control processes essential for EWB.
Conclusions
- This review provides a preliminary neural framework for understanding EWB, distinguishing modality-specific and shared neural substrates.
- Despite limitations in sample size, the findings offer an empirical foundation for future large-scale investigations into the neuroscience of EWB.
- The study highlights the importance of using consensus definitions and distinct analytical approaches for neuroimaging modalities in EWB research.

Subjective well-being (SWB) refers to an individual's self-evaluation of their overall life satisfaction, happiness, and fulfillment. This multifaceted construct is typically assessed by analyzing the balance of positive and negative emotions alongside perceptions of life satisfaction. Personality traits such as neuroticism and extraversion are strongly associated with variations in SWB, offering critical insights into the underlying mechanisms of emotional well-being.

Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...
The physiology of emotions is a multifaceted process involving the autonomic nervous system, brain structures, hormones, and neurotransmitters. This intricate interplay dictates how emotions manifest in the body and influence behavior.
Autonomic Nervous System
The autonomic nervous system (ANS) plays a critical role in emotional responses by regulating involuntary physiological functions. It consists of two main components: the sympathetic and parasympathetic systems. The sympathetic system...
Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.
Empathy is often confused with pity and sympathy, which are different reactions to the situation of someone else or...
The significance of social relationships in psychological well-being is a well-established area of inquiry within social psychology. Research consistently demonstrates that the presence of meaningful, supportive relationships enhances emotional health, while the absence or deterioration of such connections can contribute to psychological distress. Relationships serve as a foundation for emotional support, identity, and social belonging, all of which are critical to an individual’s overall...
Emotions play a fundamental role in shaping human experience and interactions. The absence of emotions would render life incomplete and fail to capture the essence of human nature. In social psychology, feelings and moods have been extensively studied due to their profound impact on social life and interpersonal relationships. These affective states influence decision-making, behavior, and social perceptions, making them integral to understanding human interactions.Emotions and Social...
