MoLo (More Locations): EEG Electrode Interpolation Algorithm

This algorithm uses spline interpolation to compute 3D EEG electrode coordinates from a subset of previously-measured positions.

EEG electrode localization may limit valuable time for data collection and is burdensome on both researcher and patient, particularly in high-density EEG (32-128 channels). We developed an algorithm, named MoLo, to compute 3D electrode coordinates from a subset of positions using spline interpolation. MoLo location accuracy is comparable to stylus digitizers and camera-scanners, common in clinical research. The algorithm is particularly useful for research involving young children and others who cannot remain still for extended time periods.
