“…In this frequency band, CNS depressors are associated with an increase of EEG power and stimulants are associated with a reduction of power over the entire scalp (40). In the present study, a reduction of absolute power was observed on the entire scalp.…”

“…For example, in rats, systemic administration of 10 mg/kg indomethacin reduces CBF by 30 -50% (32) but does not affect sleep (37). Similarly, a decrease in CBF induced by indomethacin or hyperventilation does not diminish EEG SWA in humans (28).…”

“…The underlying causes for the influence of exercise on power spectra EEG are however, far from clear, although speculations are made. When a decrease in cerebral blood flow occurs because of anoxia or hypoxia, a decrease in beta (and alpha) activity is observed 6 . If exercise promotes increased cerebral blood flow, an EEG spectral pattern opposite to that is obtained.…”

“…In this context, it has been suggested that EEG might be especially appopriate for examining the effects of physical fatigue caused by maximal exercise 3 . Changes in the brain electrical activity following exercise might be caused by different factors, such as: changes in body temperature and arousal levels by hypothalamic modulation 4,5 , alterations in cerebral blood flow 6,7 and individual emotional state 8,9 . hence, cortical activation following exercise is also related to alterations in EEG frequency bands, such as alpha (8-13 hz) and beta (14-30 hz) 10 .…”
