Intrinsic Functional Connectivity of the Anterior Cingulate Cortex Is Associated with Tolerance to Distress

Area of Science:

• Neuroscience
• Psychology
• Cognitive Science

Background:

• Psychological resilience enables adaptation to adversity and prevention of stress-related disorders.
• Distress tolerance, the ability to endure affective distress during goal pursuit, is a crucial component of resilience.
• The neural underpinnings of distress tolerance, particularly the role of intrinsic functional brain networks, remain underexplored.

Purpose of the Study:

• To investigate the relationship between baseline functional connectivity of the anterior cingulate cortex (ACC) and behavioral performance under distress.
• To test the hypothesis that ACC functional connectivity influences distress tolerance.
• To identify neural mechanisms associated with interindividual differences in persisting through challenging situations.

Main Methods:

• A cohort of 97 participants completed the behavioral indicator of resiliency to distress (BIRD) task to assess distress tolerance.
• Participants were categorized based on task completion: persistent (n=46) versus those who quit (n=51).
• Seed-based functional connectivity (FC) analyses were performed using resting-state fMRI data, focusing on the ACC.

Main Results:

• Individuals who persisted on the BIRD task exhibited greater baseline functional connectivity between the ACC and the dorsolateral prefrontal cortex (DLPFC).
• Conversely, participants who quit the task showed greater baseline functional connectivity between the ACC and the precentral gyrus.
• These findings link specific intrinsic brain network interactions with the capacity to tolerate distress.

Conclusions:

• Baseline functional connectivity patterns, particularly involving the ACC, are associated with individual differences in distress tolerance.
• The ACC's connectivity with regions like the DLPFC may support persistence under distress.
• Understanding these neural mechanisms can inform strategies for enhancing resilience and managing stress-related conditions.
