Decreased Alertness Reconfigures Cognitive Control Networks.
Canales-Johnson A, Beerendonk L, Blain S, Kitaoka S, Ezquerro-Nassar A, Nuiten S, Fahrenfort J, van Gaal S, Bekinschtein TA. Canales-Johnson A, et al. J Neurosci. 2020 Sep 9;40(37):7142-7154. doi: 10.1523/JNEUROSCI.0343-20.2020. Epub 2020 Aug 12. J Neurosci. 2020. PMID: 32801150 Free PMC article.
However, the typical neural markers of cognitive control-local midfrontal theta-band power changes-that participants show during full alertness were no longer noticeable when alertness decreased. Instead, when drowsy, we found an increase in long-range inform …

Daytime melatonin and light independently affect human alertness and body temperature.
Lok R, van Koningsveld MJ, Gordijn MCM, Beersma DGM, Hut RA. Lok R, et al. J Pineal Res. 2019 Aug;67(1):e12583. doi: 10.1111/jpi.12583. Epub 2019 May 9. J Pineal Res. 2019. PMID: 31033013 Free PMC article. Clinical Trial.
Melatonin and core body temperature levels at those times of day may contribute to differences in alerting effects of light. In this experiment, the combined effect of daytime exogenous melatonin administration and light intensity on alertness, body temperature, and …

Decreasing Alertness Modulates Perceptual Decision-Making.
Jagannathan SR, Bareham CA, Bekinschtein TA. Jagannathan SR, et al. J Neurosci. 2022 Jan 19;42(3):454-473. doi: 10.1523/JNEUROSCI.0182-21.2021. Epub 2021 Nov 23. J Neurosci. 2022. PMID: 34815316 Free PMC article.
Despite extensive work on decision-making mechanisms/models, understanding the effects of alertness on neural and cognitive processes remain limited. Here we use EEG and behavioral modeling to characterize cognitive and neural dynamics of perceptual decision-making in awak …

Decreased functional connectivity and structural deficit in alertness network with right-sided temporal lobe epilepsy.
Gao Y, Zheng J, Li Y, Guo D, Wang M, Cui X, Ye W. Gao Y, et al. Medicine (Baltimore). 2018 Apr;97(14):e0134. doi: 10.1097/MD.0000000000010134. Medicine (Baltimore). 2018. PMID: 29620625 Free PMC article.
Patients with temporal lobe epilepsy (TLE) often suffer from alertness alterations. However, specific regions connected with alertness remain controversial, and whether these regions have structural impairment is also elusive. ...Also significantly negative correlat …

Blue blocker glasses as a countermeasure for alerting effects of evening light-emitting diode screen exposure in male teenagers.
van der Lely S, Frey S, Garbazza C, Wirz-Justice A, Jenni OG, Steiner R, Wolf S, Cajochen C, Bromundt V, Schmidt C. van der Lely S, et al. J Adolesc Health. 2015 Jan;56(1):113-9. doi: 10.1016/j.jadohealth.2014.08.002. Epub 2014 Oct 3. J Adolesc Health. 2015. PMID: 25287985
RESULTS: Compared with clear lenses, BB significantly attenuated LED-induced melatonin suppression in the evening and decreased vigilant attention and subjective alertness before bedtime. ...CONCLUSIONS: BB glasses may be useful in adolescents as a countermeasure fo …

The effect of phasic alertness on temporal precision.
Li Q, Liu P, Huang S, Huang X. Li Q, et al. Atten Percept Psychophys. 2018 Jan;80(1):262-274. doi: 10.3758/s13414-017-1418-2. Atten Percept Psychophys. 2018. PMID: 29047031
Many previous studies have found that there is a close relationship between attention and temporal precision. As a mechanism that regulates the intensity of attention, alertness has beneficial influences on perceptual processing. However, little is known regarding whether …

Tracking wakefulness as it fades: Micro-measures of alertness.
Jagannathan SR, Ezquerro-Nassar A, Jachs B, Pustovaya OV, Bareham CA, Bekinschtein TA. Jagannathan SR, et al. Neuroimage. 2018 Aug 1;176:138-151. doi: 10.1016/j.neuroimage.2018.04.046. Epub 2018 Apr 23. Neuroimage. 2018. PMID: 29698731
A major problem in psychology and physiology experiments is drowsiness: around a third of participants show decreased wakefulness despite being instructed to stay alert. In some non-visual experiments participants keep their eyes closed throughout the task, thus pro …

Beyond the three-process model of alertness: estimating phase, time on shift, and successive night effects.
Folkard S, Akerstedt T, Macdonald I, Tucker P, Spencer MB. Folkard S, et al. J Biol Rhythms. 1999 Dec;14(6):577-87. doi: 10.1177/074873099129000911. J Biol Rhythms. 1999. PMID: 10643755 Review.
In light of this, we have examined two large sets of alertness ratings with a view to further refining the model and identifying additional factors that may influence alertness at any given point in time. ...Finally, we were able to identify a "time on shift" effect …
