A potential limitation of a motor imagery (MI) based brain-computer interface (BCI) is that it
usually requires a relatively long time to record sufficient electroencephalogram (EEG) data …

In many cases, observed brain signals can be assumed as the linear mixtures of unknown
brain sources/components. It is the task of blind source separation (BSS) to find the sources …

There have been several recent studies that used sparse representation for fMRI signal
analysis and activation detection based on the assumption that each voxel's fMRI signal is …

For decades, it has been largely unknown to what extent multiple functional networks
spatially overlap/interact with each other and jointly realize the total cortical function. Here …

A relatively underexplored question in fMRI is whether there are intrinsic differences in terms
of signal composition patterns that can effectively characterize and differentiate task-based …
