Key result
EEG synchronization records effectively reflected the rise in fatigue levels and drop in alertness of subjects experiencing increased cognitive loading during an Auditory Response Test.
Observational
EEG synchronization parameters can effectively measure drops in alertness and increased fatigue during cognitive loading.

EEG synchronization may track cognitive fatigue; leaves open validation before any clinical monitoring use.
A drop in alertness is likely to be induced by continuous and repetitive performance of cognitive tasks. EEG has been identified as a significant marker of changes in alertness during performance of a repeated task set. The present paper analyses the drop in alertness of subjects due to increase in fatigue levels using the variation in parameters of brain networks formed from synchronization values of EEG recorded during the performance of an Auditory Response Test. The results show the efficacy of using EEG records to reflect rise in fatigue levels of subjects with increase in cognitive loading.

Sengupta et al. (2017) conducted an observational in Cognitive fatigue. Cognitive loading during an Auditory Response Test was evaluated on Drop in alertness and rise in fatigue levels measured via EEG synchronization brain network parameters. EEG synchronization records effectively reflected the rise in fatigue levels and drop in alertness of subjects experiencing increased cognitive loading during an Auditory Response Test.
