This paper proposes a new method for analyzing brain activity from Electroencephalogram (EEG) based on a concept of instantaneous equivalent bandwidths (IEBWs). The essence of the method using the IEBW is to track bandwidths changes of EEG signals. The instantaneous equivalent band- widths are defined using positive time-frequency distributions. However, it is well known that non-negative bilinear distributions that satisfy the marginals do not exist. To solve the problem, Copula-based time…

TLDR
Electroencepharogram signals while the subjects were trying to maintain wakefulness state against sleepiness had wide bandwidth compared to the EEG signals in normal sleep onset because of the EEG desynchronization.
EEG-based Drowsiness Detection for Safe Driving Using Chaotic Features and Statistical Tests
TLDR
It is shown that chaotic features can create 95% significance level of difference between drowsiness and alertness in each EEG channels by applying the two-tailed t-test.

TLDR
The EEG signals of the frontal area in the arousal maintenance state against sleepiness have wide bandwidth as in the EEG of the occipital area, which strengthens speculation, i.e., the EEG desynchronization occurs because of the neuron activities from the frontal lobe to hypothalamus in order to maintain arousal state againstSleepiness.
Spectral characteristics assessment in recognition of drivers' drowsiness using statistical tests
TLDR
It is shown which of these frequency characteristics can create a significant difference up to 95% between alertness and drowsiness signals, and in the future studies can be used as indexes for drowsness in order to increase the drivers' safety.
