fMRI neurofeedback using the Matter app for depression

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study uses the Matter Neuroscience mobile app together with functional MRI neurofeedback sessions to train participants to recognize and increase brain activity linked to positive emotions. Participants will complete in-person fMRI neurofeedback visits at Stanford and perform app-based home training using personal or stock photos. Eligible adults (18–80) must have nonpsychotic major depressive disorder with MADRS scores 15–25, own a compatible iPhone, and have 1–5 prior adequate antidepressant failures with stable dosing. The primary goals are to gather safety data, preliminary efficacy signals, and feasibility information to inform a future pivotal trial.
