Brain Stimulation Rewires Reward Learning Without Surgery
Scientists have successfully altered human reward learning using a non-invasive brain stimulation technique. The study, led by Dr. Michael Schleußner at the University of Tübingen, targeted a deep brain region linked to motivation. Findings suggest the method could help treat conditions like addiction and depression symptoms without surgery.
The research focused on the nucleus accumbens, a small brain area that activates during pleasurable experiences. This region helps people learn behaviours that lead to rewards. Using transcranial ultrasound stimulation (TUS), the team temporarily influenced its activity.
The findings highlight TUS as a potential tool for reshaping faulty reward circuits in mental health conditions. Unlike invasive procedures, this method offers a non-surgical alternative. Further research could explore its use in treating addiction, depression tests, and eating disorders.
