Brain-Computer interfaces have been used for the rehabilitation of motor and cognitive functions. They can be used to train voluntary neural activity, leading to behavioral effects depending on the targeted brain areas.
The aim of this study was to test the feasibility of achieving volitional control of M1-cerebellum functional connectivity with a real-time fMRI (Rt-fMRI) system and evaluates its influence in motor performance.
Nine healthy subjects were trained in a protocol with visual feedback and motor imagery.
The results indicate that voluntary self-regulation of cerebellum-M1 connectivity is feasible with Rt-fMRI, but the effects on motor performance need to be further studied.
