Speeded near infrared spectroscopy (NIRS) response detection. [PDF]
PLoS ONE, 2010 The hemodynamic response measured by Near Infrared Spectroscopy (NIRS) is temporally delayed from the onset of the underlying neural activity. As a consequence, NIRS based brain-computer-interfaces (BCIs) and neurofeedback learning systems, may have a ...
