The aim of this study is to develop real-time platform for functional connectivity and activation using real-time fMRI. We performed the motion fMRI experiments, and visualized the functional connectivity and activation for the ongoing paradigm. On 3.0T MRI scanner, fMRI scanning was performed using EPI sequences with TR=3sec. Online correlation coefficients as regional functional connectivity and task-related activations were calculated and simultaneously visualized for 116 brain regions. We demonstrated the feasibility of real-time fMRI monitoring for the functional connectivity. It was possible to monitor the functional activity in real time environments, and to localize the subjects task performance.
