Published in 2022 at "Human brain mapping"

DOI: 10.1002/hbm.25851

Abstract: A well-documented amygdala-dorsomedial prefrontal circuit is theorized to promote attention to threat ("threat vigilance"). Prior research has implicated a relationship between individual differences in trait anxiety/vigilance, engagement of this circuitry, and anxiogenic features of the… read more here.

Published in 2023 at "Journal of the experimental analysis of behavior"

DOI: 10.1002/jeab.832

Abstract: Previous studies have found that infrequent targets can reduce dogs' vigilance. The purpose of this study was to develop a laboratory model to evaluate the effects of infrequent targets on dogs' search behavior and performance.… read more here.

Published in 2023 at "Journal of Neuroscience Research"

DOI: 10.1002/jnr.25182

Abstract: The maintenance of vigilance relies on the activation of the cerebral cortex by the arousal system centered on the brainstem. Previous studies have suggested that both objective and subjective vigilance are susceptible to sleep deprivation.… read more here.

Published in 2018 at "Handbook of experimental pharmacology"

DOI: 10.1007/164_2017_84

Abstract: In the present chapter, hypotheses on the mechanisms responsible for the genesis of the three vigilance states, namely, waking, non-rapid eye movement (non-REM) also called slow-wave sleep (SWS), and REM sleep also called paradoxical sleep… read more here.

Published in 2019 at "Animal Behaviour"

DOI: 10.1016/j.anbehav.2019.02.017

Abstract: Animals may form groups for different reasons, and one major benefit of grouping in many species is reduced predation risk. In diurnal species, vigilance is used to detect predators, resulting in a trade-off between feeding… read more here.

Published in 2018 at "Behavioural Processes"

DOI: 10.1016/j.beproc.2018.07.008

Abstract: Predation is a very powerful force that shapes many ungulate traits. It is widely known that increasing vigilance intensity is costly and leads to a decline of forage intake. Consequently, ungulates gather into larger groups… read more here.

Published in 2019 at "Clinical Neurophysiology"

DOI: 10.1016/j.clinph.2019.06.007

Abstract: OBJECTIVE It has been reported that sleep deprivation affects the neurophysiological mechanisms underpinning the vigilance. Here, we tested the following hypotheses in the PharmaCog project (www.pharmacog.org): (i) sleep deprivation may alter posterior cortical delta and… read more here.

Published in 2022 at "Consciousness and Cognition"

DOI: 10.1016/j.concog.2021.103263

Abstract: Previous research has shown opposite effects of dual tasking on the vigilance decrement phenomenon. We examined the executive (i.e., detecting infrequent critical signals) and arousal (i.e., sustaining a fast reaction to stimuli without much control… read more here.
