Dynamic Cortical Activity during Spasms in Three Patients with West Syndrome: A Multichannel Near‐infrared Spectroscopic Topography Study

Summary:  Purpose: To investigate spatial and temporal cortical activity during clusters of naturally occurring epileptic spasms in patients with West syndrome (WS) by using multichannel near‐infrared spectroscopy (mNIRS).
