This paper presents the first comprehensive review on vigilance enhancement using both
conventional and unconventional means, and further discusses the resulting contradictory …

Following an acute COVID-19 infection, a large number of patients experience persisting
symptoms for more than four weeks, a condition now classified as Long-COVID syndrome …

Vigilance—maintaining a prolonged state of preparation to detect and respond to specific
yet unpredictable environmental changes—usually decreases across prolonged tasks …

Cognitive fatigue is one of the most frequent symptoms in multiple sclerosis (MS), associated
with significant impairment in daily functioning and quality of life. Despite its clinical …

Abstract Gamma oscillations (30–80 Hz) are well-known for their role in cortical signal
transmission and cognitive brain functions. Aberrant gamma activity has been observed in …

Working memory (WM) is a complex cognitive function involved in the temporary storage
and manipulation of information, which has been one of the target cognitive functions to be …

Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation used
for improving cognitive functions via delivering weak electrical stimulation with a certain …

Research has shown the effectiveness of motor imagery in patient motor rehabilitation.
Transcranial electrical stimulation has also demonstrated to improve patient motor and non …

In this paper, we propose a novel vigilance enhancement method based on audio
stimulation of pure tone at 250 Hz. We induced two different levels of vigilance state; …

While zero-phase lag synchronization between multiple brain regions has been widely
observed, relatively recent reports indicate that systematic phase delays between cortical …
