INTEGRATED NIRS-EEG LAYOUTS

NIRx NIRS probes may be placed alongside EEG or other integrated cap measurement modality probes (e.g., tDCS, cochlear implants, accelerometer, etc.). It is not necessary for NIRS positions (or EEG, for that matter) to be in the standard layout.  Cap montage is flexible. 

Right: a 32-position 'standard' EEG layout with an 8-source/8-detector NIRS layout for prefrontal/SMA measurements.  

Each electrode is light blue, each source is red, each detector is green, and each 'NIRS channel of interest' is purple.  

In this case there are 20 NIRS channels from the 16-probe layout.
