Functional near-infrared spectroscopy (fNIRS) and functional magnetic resonance imaging (fMRI) are non-invasive methods for acquiring hemodynamic signals from the brain with the primary benefit of anatomical specificity of signals. Recently, there has been a surge of interest in fNIRS and fMRI for the implementation of a brain-computer interface (BCI), for the acquisition, decoding and regulation of hemodynamic signals in the brain, and to investigate their behavioral consequences and rehabilitation approaches. Both NIRS and fMRI rely on the measurement of the task-induced blood oxygen level-dependent response. In this talk, I will present the fundamental principles, recent developments, applications and future directions and challenges of NIRS-based and fMRI-based brain-computer interfaces and rehabilitations approaches. 

In addition, I will also outline my group’s research in brain connectomics and multimodal imaging.
