Summary

This study tested a non-invasive brain stimulation technique called temporal interference stimulation (TI) to improve depression in people with bipolar disorder. Thirty-six participants received 10 sessions over two weeks, targeting a deep brain area linked to pleasure and reward. The goal was to see if TI can safely reduce depressive symptoms and help understand how the brain's reward circuits work in bipolar depression.
