“…Blinks occur in response to threats to the eye but also spontaneously every 5–10 s in daily life ( Barbato et al, 2000 ). Blinks not only disrupt vision ( Volkmann et al, 1980 ; Hari et al, 1994 ; Maus et al, 2017 ) but are also involved in social communication ( Nakano and Kitazawa, 2010 ) and cognitive processing ( Hoppe et al, 2018 ; Liu et al, 2020 ). For example, blinking has been shown to occur at key break points during the flow of information giving the brain a moment to reset or reallocate attention ( Nakano et al, 2013 ).…”

“…They reported that blink-related delta oscillations could represent brain processes associated with selfconsciousness and environmental awareness [19]. Unlike resting state studies, Liu et al [21] demonstrated that blink-related activities are dynamically regulated to match internal cognitive processing demands in varied external settings during a task that requires repetitive reading. Additionally, they confirmed in another [22] that the areas of the ventral attention network are engaged during blink-related mental arithmetic tasks.…”

Evaluating and understanding the cognitive demands of natural activities has been difficult using neurocognitive approaches like mobile EEG. While taskunrelated stimuli are commonly added to a workplace simulation to estimate event-related cognitive processes, using eyeblink activity poses an alternative as it is inherent to human behavior. This study aimed to investigate the eye blink event-related EEG activity of fourteen subjects while working in a power-plant operator simulationactively operating (active condition) or observing (passive condition) a real-world steam engine. The changes in event-related potentials, event-related spectral perturbations, and functional connectivity under both conditions were analyzed. Our results indicated several cognitive changes in relation to task manipulation. Posterior N1 and P3 amplitudes revealed alterations associated with task complexity, with increased N1 and P3 amplitudes for the active condition, indicating greater cognitive effort than the passive condition. Increased frontal theta power and suppressed parietal alpha power were observed during the active condition reflecting high cognitive engagement. Additionally, higher theta connectivity was seen in frontoparieto-centro-temporo-occipital regions as task demands increased, showing increased communication between brain regions. All of these results suggest using eye blinkrelated EEG activity to acquire a comprehensive understanding of neuro-cognitive processing while working in realistic environments.

“…Artifact Removal: Recently, Liu et al 71 provided compelling evidence that blink-related processes are dynamically modulated not only to accommodate internal cognitive loading demands but also to address specific sensory processing requirements due to differences in the external environment. It is evident that not only at rest condition but also during a work task involving repeated reading, eye blinking occurs and is accompanied by an oscillatory activity 72 .…”

Extreme conditions affect neuronal oscillations of cerebral cortices in humans in the China Space Station and on Earth

Rhythmical oscillations of neural populations can reflect working memory performance. However, whether neuronal oscillations of the cerebral cortex change in extreme environments, especially in a space station, remains unclear. Here, we recorded electroencephalography (EEG) signals when volunteers and astronauts were executing a memory task in extreme working conditions. Our experiments showed that two extreme conditions affect neuronal oscillations of the cerebral cortex and manifest in different ways. Lengthy periods of mental work impairs the gating mechanism formed by theta-gamma phase-amplitude coupling of two cortical areas, and sleep deprivation disrupts synaptic homeostasis, as reflected by the substantial increase in theta wave activity in the cortical frontal-central area. In addition, we excluded the possibility that nutritional supply or psychological situations caused decoupled theta-gamma phase-amplitude coupling or an imbalance in theta wave activity increase. Therefore, we speculate that the decoupled theta-gamma phase-amplitude coupling detected in astronauts results from their lengthy periods of mental work in the China Space Station. Furthermore, comparing preflight and inflight experiments, we find that long-term spaceflight and other hazards in the space station could worsen this decoupling evolution. This particular neuronal oscillation mechanism in the cerebral cortex could guide countermeasures for the inadaptability of humans working in spaceflight.
