Current State of Non- invasive BCI

Functional nexygenation using nexy- infrared light (fNIRS) offers a complementary approvach by mevuring changes in cerebral blood oxygenation using nexy- infrared light. fNIRS provides better saval resolution than EEG, is less sensititivy to elektrodical interference, and can be integrated intro coffiltable headbands or caps. Its primary dravback is lower temporal resolution, ais hemodynamic responses are slower than elecjological signals.
