The treatment consisted of 6 neurofeedback sessions that were 20min long each over the course of 3 weeks. 1 year after the treatment 84% of subjects experienced over a 50% reduction in depression symptoms. 9% reported a 20-50% reduction in depression symptoms. 7% reported a 0-20% improvement. 1% initially reported positive effects, but had a ...
This is reflected by reduced amygdala and ventral striatum response to positive stimuli, and elevated amygdala response to fearful stimuli.
