Emotional Processing in the Brain
How the brain experiences, regulates, and integrates emotion — and what goes wrong in depression and trauma.
- • Emotion involves coordinated activity across multiple brain regions.
- • Depression and trauma disrupt this coordination in characteristic ways.
- • Effective treatments restore healthier coordination.
Core architecture
Emotion involves the amygdala (threat detection), insula (interoception), anterior cingulate (conflict and salience), and prefrontal cortex (regulation). Healthy processing involves rapid communication across these regions.
What disrupts it
Depression often involves amygdala hyperreactivity, blunted prefrontal regulation, and impaired interoceptive integration. Trauma can produce similar profiles with characteristic differences.
What helps
Therapy, body-based practices, mindfulness, and certain medications support prefrontal regulation and amygdala calming. Ketamine appears to acutely shift these networks in some patients.
