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

Disposables

For the preparation of the subjects you need all types of disposables like alcohol, lotion, cotton pads, electrolyte gel, etc... You can find information about these items in NIRS-EEG lab disposables, and also info where to order them when needed.

Kitchen

EEG/NIRS kitchen

A small kitchen is available for washing the hair of the subject and for cleaning caps and other equipment afterwards.

FIRST AID (EHBO)

Above the kitchen on the right there is a FIRST AID-kit on the wall.
