Neural correlates linked to developmental and affective disorder-related self-referential processing: an ALE...

Area of Science:

• Neuroscience
• Developmental Psychology
• Cognitive Science

Background:

• Adolescence is a critical period for self-development, marked by differential maturation of emotion and cognition brain networks.
• This developmental trajectory may increase vulnerability to mental health conditions like depression and social anxiety disorder.
• Previous functional magnetic resonance imaging (fMRI) studies on self-referential processing (SRP) show mixed results due to methodological variability.

Purpose of the Study:

• To conduct the first activation likelihood estimation meta-analysis of SRP.
• To confirm the brain network associated with SRP.
• To investigate age- and disorder-related neural correlates of SRP and explore task design moderators.

Main Methods:

• Meta-analysis of 33 task-based fMRI studies.
• Inclusion of healthy controls, community samples, and clinical samples (socially anxious or depressed).
• Analysis focused on activation likelihood estimation to synthesize findings.

Main Results:

• Confirmed robust SRP-related activation in core hubs of the default mode network.
• Observed age-related differences: stronger anterior cingulate cortex activation in younger groups (children, adolescents, emerging adults) versus adults.
• Adults showed stronger dorsolateral prefrontal cortex activity; clinical samples lacked significant convergence; task design moderated neural activation.

Conclusions:

• Findings support the developmental maturation of self-representational processes.
• Highlights the importance of methodological considerations in future SRP research.
• Suggests potential neural markers for understanding developmental trajectories and vulnerability to affective disorders.
