Discrimination of temporal fatigue-related states and inferred brain-function coupling in subway drivers under emotional influence

IntroductionThe mental fatigue state of subway drivers directly affects operational safety. At the same time, they are easily influenced by individual emotions and are closely related to the state of brain function.MethodsIn this study, multimodal data of subway drivers during driving were collected synchronously in a simulated driving environment, including EEG signals, subjective fatigue perception, emotional states and operational performance data. First, the Toeplitz inverse covariance clust
