Recognition of hemodynamic responses for mental arithmetic using support vector machine

Functional near infrared spectroscopy (fNERS) is a non-invasive technology that can be applied in brain-computer interface (BCI). fNIRS uses light in the range of near infrared to measure activity of the cerebral cortex. Prefrontal cortex is activated when performing mental arithmetic tasks. We captured frontal hemodynamic responses during mental arithmetic task from two subjects. Two different brain activities, rest and active, are recognized using Support Vector Machine (SVM). Task onset delay can be reduced by selecting appropriate feature set.
