The brain connectome collects the complex network architectures,looking at both static and dynamic functional connectivity.The former normally requires stationary signals and connections.However,the human brain activity and connections are most likely time dependent and dynamic,and related to ongoing rhythmic activity.We developed an open-source MATLAB toolbox DynamicBC with user-friendly graphical user interfaces,implementing both dynamic functional and effective connectivity for tracking brain dynamics from functional MRI.We believe that this toolbox will help neuroscientists and neurologists to map easily dynamic brain connectomics.
