摘要

It has been reported as the measurements of cerebral activity by EEG and otherneurophysiologic variables such as EKG and eye blinks could be extremely useful in thecharacterization of the “internal” state of pilots and air traffic controllers. Here, we report the resultsfrom a study aimed to use a set of validated neurometric indicators for the study of the mental workloadthat could occur during simulated car drive in a group of healthy subjects. In addition, it was alsoinvestigated the insurgence of sleepiness during such driving activity. Results obtained suggest that theworkload index is sensitive to the mental efforts of the driver during the different drive tasks performed.In addition, results suggested as HR increases during the execution of the difficult driving tasks whileinstead it decreases at the insurgence of the drowsiness. The proposed workload index could be thenused in a near future to assess on-line the mental state of the driver during a drive task.
