The NIRSport 8*8 is a freely configurable, battery operated, fNIRS system comprising of 8 illumination sources and 8 detection sensors. This ultra-light system combines LED illumination and innovative active detection sensor technology to provide a truly wearable neuroimaging solution. The NIRSport also offers the ability for tandem studies with two separate systems synchronized to operate simultaneously, thus doubling the source-detector density. The NIRSport system solution provides the opportunity for researchers to pursue a wide array of neuro-imaging applications, where capturing data in open environments is the primary focus. Potential applications include: Brain Computer Interface, Autism, Driver/Pilot Vigilance, Traumatic Brain Injury Assessment and Rehabilitation, Interactive Cognition Studies and so on.
