EEG
- 32 channel water-based electrode system (TMSI, Mobita), including headcap(s)
- 72 channel REFA, including headcaps in 3 different sizes (TMSI)
- 16 channel REFA (TMSI)
- ring electrodes including separate caps for combined measurements with NIRS
- TMSI Polybench recording software
NIRS
- 2 x 24 channel system (Oxymon, Artinis) each consisting of 8 transmitters and 4 receivers (splitted fibers)
- sampling rate up to 250 Hz
- 8 AD channels (according to Artinis, they only sample at the rate of all other channels. Care needs to be taken, if sampling at low rates. Present your triggers for longer durations then)
- Oxysoft recording software
