Modern neuroscience has revealed how emotion regulation affects the brain's structure, chemistry, and function — knowledge that's transforming treatment approaches.
The Brain Regions Involved in Emotion Regulation
Key brain areas implicated in emotion regulation include:
- Amygdala: The brain's threat-detection center becomes hyperactive in emotion regulation, triggering excessive fear and stress responses
- Prefrontal Cortex: Responsible for rational thinking and emotional regulation — its function is often impaired by emotion regulation
- Hippocampus: Memory and context processing; chronic emotion regulation can affect its volume and function
- HPA Axis: The stress hormone system that, when dysregulated, drives many physical symptoms of emotion regulation
Neurochemistry of Emotion Regulation
Emotion Regulation involves imbalances or dysregulation of key neurotransmitters including serotonin, dopamine, norepinephrine, and GABA — all targets of current treatments.
How Treatment Changes the Brain
Both therapy and medication produce measurable changes in brain function in emotion regulation. CBT, for example, has been shown to normalize amygdala reactivity.
Neuroplasticity and Emotion Regulation
The brain retains its ability to change throughout life. This neuroplasticity means that with appropriate treatment and practice, the neural patterns underlying emotion regulation can genuinely change.
