TL;DR: In a proof-of-concept study, eight patients with depression learned to upregulate brain areas involved in the generation of positive emotions during four neurofeedback sessions, and their clinical symptoms improved significantly.
Neurofeedback: A promising tool for the self-regulation of emotion networks
TL;DR: The findings demonstrate the feasibility of fMRI-based neurofeedback of emotion networks and suggest a possible development into a therapeutic tool.

TL;DR: It is found that RS with support vector machines (SVM) as the base classifier outperformed single classifiers as well as some of the most widely used classifier ensembles such as bagging, AdaBoost, random forest, and rotation forest.

TL;DR: It is demonstrated that several key regions, such as the anterior insula and the basal ganglia, are consistently activated during self-regulation in real-time fMRI neurofeedback independent of the targeted region-of-interest.
