“…Other fMRI studies demonstrated that sleep pressure reduced the brain information processing efficiency (Pan et al, 2022;Qi et al, 2021), which was related to the reduction in vigilance. A progressive increase in synaptic strength reflected by cortical excitability declines signal-to-noise ratios and saturates cognitive processes, further resulting in reduced cortical communication efficiency (Porkka-Heiskanen et al, 2013;Tononi & Cirelli, 2014).…”

SummaryVigilance is highly sensitive to the time‐of‐day effect and goes through the daytime trough during the period of the post‐noon dip. A midday nap could maintain individuals’ vigilance at an optimal level. Thus, homeostatic sleep pressure is one of the main reasons for the post‐noon dip in daytime vigilance. The current study focussed on the role of homeostatic sleep pressure in the diurnal variation of vigilance performance with normal circadian rhythms and the corresponding neural basis. With 34 healthy adults, we recorded the resting‐state electroencephalogram activities and the following vigilance performance measured by psychomotor vigilance test in the morning, the no‐nap mid afternoon, and the nap mid afternoon. The circadian process was controlled by measuring vigilance and resting‐state electroencephalogram activities at the same time point in the nap and no‐nap conditions. Homeostatic sleep pressure accumulated from morning to mid afternoon induced the declined vigilance performance and a global increase in resting‐state delta, theta, alpha, and beta1 bands power, and a local increase in beta2 band power in the central region. Furthermore, the more the spontaneous beta2 power increased, the less vigilance declined from morning to mid afternoon. The current findings suggest that homeostatic sleep pressure increased cortical excitability but decreased cortical communication efficiency from morning to mid afternoon. In addition, the activity of the high beta waves probably reflected the compensatory effort to counteract the negative impact of the low arousal state on the following vigilance task by performing more action preparation in the no‐nap afternoon.

“…Mounting evidence suggests that sleep loss decreases attentional task‐related activity in the DLPFC, intraparietal sulcus, and extrastriate visual cortex (Chee et al, 2010, 2011; Chee & Tan, 2010). Also, many studies have shown that decreased spontaneous brain activity in the frontoparietal network may underlie attention deficits after sleep deprivation, especially in the DLPFC (Cai et al, 2021; Qi, Li, Zhang, Pan, Gao, Zhan, Liu, Shao, Weng, & Zhang, 2021; Xu & Wenzhong, 2021; Zhou et al, 2017). Indeed, the frontoparietal and extrastriate visual cortex were found to be involved in top‐down control and visual sensory, respectively (O'Connor et al, 2002).…”

“…Furthermore, an increasing number of studies have shown that alterations in resting‐state functional connectivity play an important role in decreased vigilance after sleep deprivation. For example, some studies found that lapses in attention after sleep deprivation were correlated with changed functional connectivity of the frontoparietal, sensorimotor, and salience networks (Qi, Li, Zhang, Pan, Gao, Zhan, Liu, Shao, Weng, & Zhang, 2021; Qi, Li, Zhang, Pan, Gao, Zhan, Liu, Shao, & Zhang, 2021; Xu & Wenzhong, 2021). On the other hand, we previously found that increased functional coupling between the salience network and default mode network predicted higher subjective ratings of sleepiness following sleep deprivation (Lei et al, 2015).…”

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. This study aims to explore the alterations in brainstem arousal system functional connectivity (FC) and its involvement in these two types of vigilance decline following total sleep deprivation (TSD). Thirty‐seven healthy male subjects underwent two counterbalanced resting‐state fMRI scans, once in rested wakefulness (RW) and once after 36 h of TSD. The pontine tegmental area and caudal midbrain (PTA‐cMidbrain), the core regions of the brainstem arousal system, were chosen as the seeds for FC analysis. The difference in PTA‐cMidbrain FC between RW and TSD conditions was then investigated, as well as its associations with objective vigilance measured by psychomotor vigilance task (PVT) and subjective vigilance measured by Stanford Sleepiness Scale. The sleep‐deprived subjects showed increased PTA‐cMidbrain FC with the thalamus and cerebellum and decreased PTA‐cMidbrain FC with the occipital, parietal, and sensorimotor regions. TSD‐induced increases in PVT reaction time were negatively correlated with altered PTA‐cMidbrain FC in the dorsolateral prefrontal cortex, extrastriate visual cortex, and precuneus. TSD‐induced increases in subjective sleepiness were positively correlated with altered PTA‐cMidbrain FC in default mode regions including the medial prefrontal cortex and precuneus. Our results suggest that different brainstem FC patterns underlie the objective and subjective vigilance declines induced by TSD.

“…The suggested small world network accomplishes power exchanging, boosts the network, increases power economy as well as minimises data, according to experimental outcomes. Qi et al [11] presented the small-world network is linked to decreased alert attention after total sleep deprivation. The findings show that topological features of networks are disturbed, and that abnormal temporal and salience network topology may operate as neural markers underpinning vigilant attention problems following total sleep deprivation (TSD).…”

Complex networks have been a prominent topic of research for several years, spanning a wide range of fields from mathematics to computer science and also to social and biological sciences. The eigenvalues of the Seidel matrix, Seidel Signless Laplacian matrix, Seidel energy, Seidel Signless Laplacian energy, Maximum and Minimum energy, Degree Sum energy and Distance Degree energy of the Unitary Cayley graphs [UCG] have been calculated. Low-power devices must be able to transfer data across long distances with low delay and reliability. To overcome this drawback a small-world network depending on the unitary Cayley graph is proposed to decrease the delay and increase the reliability and is also used to create and analyze network communication. Small-world networks based on the Cayley graph have a basic construction and are highly adaptable. The simulation result shows that the small-world network based on unitary Cayley graphs has a shorter delay and is more reliable. Furthermore, the maximum delay is lowered by 40%.
