The NIRSport system is a device capable of acquiring fNIRS signals by placing near infrared light sources and photodiodes (or detectors) directly on the scalp. In this way it is possible to monitor the hemodynamic activations of the brain during different experimental protocols. NIRSport is a portable device that can be used wirelessly, easily usable in experimental setups that involve a moving subject. This system has the following characteristics:

• 8 sources and 8 detectors
• 8 "short channels" detectors for the detection and filtering of extra-cerebral signals from the fNIRS signal
• Sources with a wavelength of 760 nm and 850 nm
• Two headsets (size M and L) with 128 holes arranged according to the 10/5 system, usable for positioning NIRS and EEG channels
• Possibility of operation with USB interface (with connection to a PC), WiFi or stand-alone
• Battery capacity: 5-6 hours
• Maximum sampling frequency: 80Hz
• Aurora recording software
• Possibility of multimodal acquisition (integrable with EEG, tDCS and eye-tracker).
