Estimating mental fatigue based on electroencephalogram and heart rate variability

The effects of long term mental arithmetic task on psychology are investigated by subjective self-reporting measures and action performance test. Based on electroencephalogram (EEG) and heart rate variability (HRV), the impacts of prolonged cognitive activity on central nervous system and autonomic nervous system are observed and analyzed. Wavelet packet parameters of EEG and power spectral ind...

Estimating VDT Mental Fatigue Using Multichannel Linear Descriptors and KPCA-HMM

The impacts of prolonged visual display terminal (VDT) work on central nervous system and autonomic nervous system are observed and analyzed based on electroencephalogram (EEG) and heart rate variability (HRV). Power spectral indices of HRV, the P300 components based on visual oddball task, and multichannel linear descriptors of EEG are combined to estimate the change of mental fatigue. The res...

Physiological Assessment of Driving Mental Fatigue Using Wavelet Packet Energy and Random Forests

This study measured multiple physiological parameters of mental fatigue induced by the simulated driving task. The subjects’ mannerisms and driving performance reveal that the driving mental fatigue is induced after long-term simulated driving. The wavelet packet energy (WPE) of EEG were used to extract the features of brain activity in the normal and the mental fatigue states, then random fore...

Dissociation between mental fatigue and motivational state during prolonged mental activity

Mental fatigue (MF) is commonly observed following prolonged cognitive activity and can have major repercussions on the daily life of patients as well as healthy individuals. Despite its important impact, the cognitive processes involved in MF remain largely unknown. An influential hypothesis states that MF does not arise from a disruption of overused neural processes but, rather, is caused by ...
