Subgenual cingulate cortex: why sadness keeps looping
A sad thought keeps coming back, you replay the same scene, and nothing seems to shift it. This page covers what the subgenual cingulate cortex does for sadness and rumination, what activates it, what settles it, and three sourced exercises.
A hub of sadness and rumination; overactive in depression and a target of deep-brain stimulation research.
- Lights up with
- sadness · rumination · negative self-referential thought
- Quiets with
- behavioral activation · positive engagement · effective treatment
- When it is strained
