FIGURE 4.2: Example of EEG rhythms and EEG power spectrum.
Beta activity is characteristic for the states of increased alertness and focused
attention, as was shown in several animal and human studies.
Gamma activity is connected with information processing, e.g., recognition of
sensory stimuli and the onset of voluntary movements. High frequency gamma
rhythms are linked to neuronal spikes. They are correlated with the degree of
functional activation of the brain and are relevant to cortical computations.
The EEG is observed in all mammals, the characteristics of primate EEG being
closest
