Modern neuroscience has revealed how emotions affects the brain's structure, chemistry, and function — knowledge that's transforming treatment approaches.
The Brain Regions Involved in Emotions
Key brain areas implicated in emotions include:
- Amygdala: The brain's threat-detection center becomes hyperactive in emotions, triggering excessive fear and stress responses
- Prefrontal Cortex: Responsible for rational thinking and emotional regulation — its function is often impaired by emotions
- Hippocampus: Memory and context processing; chronic emotions can affect its volume and function
- HPA Axis: The stress hormone system that, when dysregulated, drives many physical symptoms of emotions
Neurochemistry of Emotions
Emotions 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 emotions. CBT, for example, has been shown to normalize amygdala reactivity.
Neuroplasticity and Emotions
The brain retains its ability to change throughout life. This neuroplasticity means that with appropriate treatment and practice, the neural patterns underlying emotions can genuinely change.
