Attentional lapses are usually viewed as a result of deterioration in cognitive control. Current theories suggest that deterioration in the cognitive control may be related to an increase in alpha rhythm power, although it is not clear whether this notion can be generalized outside of the visual...

Dementia caused by Alzheimer’s disease (AD) is worldwide one of the main medical and social challenges for the next years and decades. An automated analysis of changes in the electroencephalogram (EEG) of patients with AD may contribute to improving the quality of medical diagnoses. In this...

After filtering out the α and β peaks in the power spectrum of the human brain electroencephalogram signals Y(t′), the probability distribution of the variation ΔY(t′)≡Y(t′+Δt)-Y(t′) exhibits a dynamic scaling behavior. The auto-correlation functions, persistence probabilities and...

The nature of interrelations of brain event-related potentials to behavioral measures and temperament dimensions was studied in the situation of attention under the auditory oddball paradigm. Several components of event-related potentials were found to be related to Extraversion, Mobility,...

Electroencephalogram (EEG) of Alzheimer's disease (AD) patients show a slowing effect and less synchronization. EEG signal's transient and abrupt nature is captured from various mother wavelets. However, better performance can be obtained by balancing time-frequency localization in wavelet...
