The rtFIN (real-time functional imaging neurofeedback) 2026 conference mainly focused on neuroimaging topics including functional magnetic resonance imaging (fMRI), electroencephalography (EEG), magnetoencephalography (MEG), and functional near-infrared spectroscopy (fNIRS) imaging modalities used in a real-time (closed-loop) setting to modulate brain activity in healthy individuals and in clinical populations. Growing invasive approaches such as iEEG for real-time applications will also be included.
