fNIRS probe montage
Importance of Optode Array Design
Essential to align optode arrangements with anatomical landmarks or standardized EEG locations for study consistency
Montage design
Crafting an optimal probe layout to target the specified ROI effectively
The International 10–20 system
Gold Standard
Standard for electrode placement on the scalp
Uses cranial landmarks: the nasion (Nz), inion (Iz), and preauricular points (RA, LA) to systematically position electrodes
Consistent relationship between scalp positions and underlying brain structures, validated

How to manage MeMoSoft software ?
Define the montage - Place fNIRS optodes (Sources, Detectors) and EEG electrodes on 155 anatomical different landmarks - Define max. distance - Define short-channels
Enter the participant information - Adapt to participant's anatomical landmarks (Nasion-Inion & Left aupercularis - Right aupercularis distances , head circumference)
Compute the channels - Get 3D coordinates - Get measures to place sensors on the participant's head.
