Changes in Two Eeg Rhythms during Mental Activity.
2 sets of tasks—mental addition tasks and concept tasks—were given to 12 Ss and the effects of these tasks on 2 EEG rhythms—kappa and alpha—observed. On the mental addition tasks the difficulty of the task was shown to increase the output of kappa significantly but not the output of alpha. On the concept task, however, the difficulty of the task was shown to depress the output of alpha signific...

متن کاملChanges in EEG and HRV during Event-Related Attention
Determination of attentional status is important because working performance and an unexpected accident is highly related with the attention. The autonomic nervous and the central nervous systems can reflect the changes in person’s attentional status. Reduced number of suitable pysiological parameters among autonomic and central nervous systems related signal parameters will be critical in opti...
متن کاملApplying Genetic Algorithm to EEG Signals for Feature Reduction in Mental Task Classification
Brain-Computer interface systems are a new mode of communication which provides a new path between brain and its surrounding by processing EEG signals measured in different mental states. Therefore, choosing suitable features is demanded for a good BCI communication. In this regard, one of the points to be considered is feature vector dimensionality. We present a method of feature reduction us...
متن کاملdetecting driver mental fatigue based on eeg alpha power changes during simulated driving
background: driver fatigue is one of the major implications in transportation safety and accounted for up to 40% of road accidents. this study aimed to analyze the eeg alpha power changes in partially sleep-deprived drivers while performing a simulated driving task. methods: twelve healthy male car drivers participated in an overnight study. continuous eeg and eog records were taken during driv...
