“…As previously demonstrated (Corsi-Cabrera et al 1992), EEG powers in the 0.5-7 Hz low frequency range increased with sleep deprivation, but in contrast with previous findings from shorter 40-h constant routine protocols (Cajochen et al 1995(Cajochen et al , 2000(Cajochen et al , 2001Aeschbach et al 1999;Dumont et al 1999), the d and q frequency bands isolated from this 60-h study did not show the monotonic trends, reflecting the homeostatic sleep-wake regulatory process. However, using a 0.5 Hz spectral resolution, our methodology indicated that the increase in low frequency EEG activity occurred later for the lower frequencies.…”

Distinctive effects of modafinil and d-amphetamine on the homeostatic and circadian modulation of the human waking EEG

These findings demonstrate that the alertness-promoting effects of modafinil and d-amphetamine involve distinct EEG activities and do not reside on the same vigilance regulatory processes. While d-amphetamine inhibits the expression of a sleep-related process, probably through a direct cortical activation masking EEG circadian rhythms, modafinil, through a synchronic effect, preferentially disrupts the homeostatic down-regulation of a waking drive.

“…Furthermore, the main effects of quadrant were expected once EEG activity is different in each scalp area. In addition, the differences among moments were also expected, since sleep deprivation induces changes in the qEEG variables [29][30][31] . In this sense, the main effects observed in the present study were not due to caffeine ingestion itself.…”

Caffeine is regarded as a central nervous system (CNS) stimulant. The goal of this study was to analyze electrophysiological, motor, cognitive and behavioral changes produced by caffeine ingestion after sleep deprivation. Ten subjects were evaluated after sleep deprivation, comparing the ingestion of either 400 mg of caffeine or placebo, in a double-blind randomized study. The variables analyzed were: quantitative EEG, the event-related potential (ERP-P300) and cognitive responses. The most significant quantitative EEG results, which were characterized by moment × treatment interactions, were seen in α and Θ relative power variables. A significant decrease in relative α and Θ was observed in the caffeine group after sleep deprivation. In relation to caffeine stimulant effects, there were no significant differences in the other parameters.

“…Both studies revealed a periodicity of about 18 s for both performance and EEG low theta activity during periods of relatively poor performance related to drowsiness, with the two measures correlated to one another (Makeig and Jung, 1996;. Following overnight or diurnal sleep there is an increase in interhemispheric correlations as compared to presleep baseline, with the opposite effect seen after a night of sleep deprivation (Corsi-Cabrera et al, 1992). All of these EEG changes are associated with functional impairment and therefore have potential practical applications for monitoring performance (Corsi-Cabrera, 1992;Jung, 1997).…”

Vigilance is a term with varied definitions but the most common usage is sustained attention or tonic alertness. This usage of vigilance implies both the degree of arousal on the sleep-wake axis and the level of cognitive performance. There are many interacting neural and neurotransmitter systems that affect vigilance. Most studies of vigilance have relied on states where the sleep-wake state is altered, e.g. drowsiness, sleep-deprivation, and CNS-active drugs, but there are factors ranging from psychophysics to motivation that may impact vigilance. While EEG is the most commonly studied physiologic measure of vigilance, various measures of eye movement and of autonomic nervous system activity have also been used. This review paper discusses the underlying neural basis of vigilance and its assessment using physiologic tools. Since, assessment of vigilance requires assessment of cognitive function this aspect is also discussed.
