EEG index for control operators’ mental fatigue monitoring using interactions between brain regions

作者：

Highlights：

• An on-line index of operators’ mental fatigue is proposed.

• It uses EEG signals from 6 regions of interest (ROIs).

• It measures the changes in the EEG spatial covariance matrix.

• It is highly correlated with an EOG index using Perclos.

• It is in concordance with the Karolinska Sleepiness Scale scores.
