Different EEG-vigilance stages from full alertness to sleep onset can be separated during rest. Also fMRI research recently focused on the resting condition and identified several resting state networks. In order to deepen the understanding of different levels of global brain function from relaxed wakefulness to sleep onset the association between EEG-vigilance stages and BOLD signals was analy...

Almerud, Sofia (2007). Vigilance & Invisibility. Care in technologically intense environments. Acta Wexionensia No 120/2007. ISSN: 1404-4307, ISBN: 978-91-7636569-4. Written in English with a summary in Swedish. This thesis focuses on the relationship between technology and caring in technologically intense environments. The overall aim was to uncover the meaning of care in those environments a...

Vigilance behavior may directly affect fitness of prey animals, and understanding factors influencing vigilance may provide important insight into predator-prey interactions. We used 40,540 pictures taken withcamera traps in August 2011 and 2012to evaluate factors influencing individual vigilance behavior of white-tailed deer (Odocoileus virginianus) while foraging at baited sites. We used bina...

the early and accurate diagnosis of an infectious agent is essential for successfully treating individual patients and is even more important at the population or global level. the ability to identify quickly the causative pathogen of an emerging epidemic or pandemic markedly increases the chances of success of any countermeasures to contain the disease. For this reason, many countries together...

Cognitive fatigue emerges in wide-ranging tasks and domains, but traditional vigilance tasks provide a well-studied context in which to explore the mechanisms underlying it. Though a variety of experimental methodologies have been used to investigate cognitive fatigue in vigilance, relatively little research has utilized electroencephalography (EEG), specifically event-related potentials (ERPs)...

Paper presents some aspects regarding the technological vigilance as a good and efficient instrument used in enterprise evaluation. It is known that the technological vigilance is an effort of an organization in the way to observe, analyze, receive, disseminate and retrieve information about the competitiveness in time. Technological vigilance means monitoring, observing, checking and updating ...

Both physical and mental effort are thought to affect vigilance. Mental effort is known for its vigilance declining effects, but the effects of physical effort are less clear. This study investigated whether these two forms of effort affect the EEG and subjective alertness differently. Participants performed a physical task and were subsequently presented with a mental task, or vice versa. Ment...

—This study was designed to test hypotheses regarding vigilance (a state of alertness that allows an animal to detect the presence of predators or other threats) in whitetailed deer (Odocoileus virginianus). Based on findings on other species, we predicted that: (1) increasing group size would result in decreased individual vigilance; (2) juveniles would be less vigilant than adults; and (3) ma...

We developed and tested a neuroergonomic smartphone application called Mind Metrics that can be used to evaluate vigilance and working memory under naturalistic conditions. The application met a requirement to the field of neuroergonomics because the cognitive tasks were made for a smartphone platform, allowing the ability to make predictions about the neural processes that impact human perform...

Vigilance tasks, from driving to surveillance to security remain important and frequent tasks for the US Army. Yet the difficulty users have sustaining vigilance is well known. Augmented cognition offers new methods for supporting sustained vigilance via a closed-loop attention management system (CLAM). A CLAM system monitors operators’ psychophysiology for signs of inattention and then trigger...
