“…However, other reports have indicated a decrease in the activation of the parietal cortex after sleep deprivation (Almklov et al, 2015). Moreover, the results revealed that the decrease in activation was significantly correlated with a decrease in short-term memory after sleep deprivation (Adrienne, 2013; Xie et al, 2015; Nicolas et al, 2016; Julien et al, 2017). Previous study using an n-back task to test WM in participants who had been sleep-deprived for 24 h found that sleep deprivation leads to a reduction in metabolic activity in the brain’s regional network (prefrontal cortex, anterior cingulate gyrus, thalamus, and cerebellum) mainly involved in information processing and executive control (Choo et al, 2005).…”

Decreased Information Replacement of Working Memory After Sleep Deprivation: Evidence From an Event-Related Potential Study

Working memory (WM) components are altered after total sleep deprivation (TSD), both with respect to information replacement and result judgment. However, the electrophysiological mechanisms of WM alterations following sleep restriction remain largely unknown. To identify such mechanisms, event-related potentials were recorded during the n-back WM task, before and after 36 h sleep deprivation. Thirty-one young volunteers participated in this study and performed a two-back WM task with simultaneous electroencephalography (EEG) recording before and after TSD and after 8 h time in bed for recovery (TIBR). Repeated measures analysis of variance revealed that, compared to resting wakefulness, sleep deprivation induced a decrease in the P200 amplitude and induced longer reaction times. ERP-component scalp topographies results indicated that such decrease primarily occurred in the frontal cortex. The N200 and P300 amplitudes also decreased after TSD. Our results suggest that decreased information replacement of WM occurs after 36 h of TSD and that 8 h TIBR after a long period of TSD leads to partial restoration of WM functions. The present findings represent the EEG profile of WM during mental fatigue.

“…Recently, it was shown that an improvement of WM perfomance after post-training sleep compared with an equivalent period of wakefulness, suggesting the beneficial effects of sleep on WM ability (Kuriyama et al, 2008). Similarly, it has also been demonstrated that our ability to attend to and maintain information in WM is severely affected by sleep deprivation (Chee and Choo, 2004;Drummond et al, 2012;Wee et al, 2013).…”

Summary In the present study we investigated whether one night of sleep deprivation can affect working memory (WM) performance with emotional stimuli. Twenty‐five subjects were tested after one night of sleep deprivation and after one night of undisturbed sleep at home. As a second aim of the study, to evaluate the cumulative effects of sleep loss and of time‐of‐day changes on emotional WM ability, the subjects were tested every 4 h, from 22:00 to 10:00 hours, in four testing sessions during the sleep deprivation period (deprivation sessions: D1, D2, D3 and D4). Subjects performed the following test battery: Psychomotor Vigilance Task, 0‐back task, 2‐back task and an ‘emotional 2‐back task’ with neutral, positive and negative emotional pictures selected from the International Affective Picture System. Results showed lower accuracy in the emotional WM task when the participants were sleep‐deprived relative to when they had slept, suggesting the crucial role of sleep for preserving WM ability. In addition, the accuracy for the negative pictures remains stable during the sessions performed from 22:00 to 06:00 hours (D1, D2 and D3), while it drops at the D4 session, when the participants had accumulated the longest sleep debt. It is suggested that, during sleep loss, attentional and WM mechanisms may be sustained by the higher arousing characteristics of the emotional (negative) stimuli.

“…This sets a major constraint on a wide range of cognitive and affective processes, such as attention (Kane, Poole, Tuholski, & Engle, 2006), fluid intelligence (Conway, Cowan, Bunting, Therriault, & Minkoff, 2002), processing of affective information (Lynn et al, 2016; Xie et al, 2017), and emotional regulation (Schmeichel, Volokhov, & Demaree, 2008). In addition, compromised WM is also frequently associated with declines in various health-related factors, such as poor sleep quality (e.g., Wee, Asplund, & Chee, 2013), depressed mood (e.g., Xie et al, 2018a), and age (e.g., Peich, Husain, & Bays, 2013), suggesting the importance of WM assessment in translational research.…”

“…For example, naturally-occurring and experimentally-induced sleep loss can significantly impair WM (Chee & Chuah, 2007; Smith, McEvoy, & Gevins, 2002; F. Waters & Bucks, 2011; Wee et al, 2013). Although these impairments have been taken as evidence for reduced WM capacity (i.e., the amount of information maintained in WM), a reduction in memory quality might also account for these findings (see Xie & Zhang, 2016; 2017a; 2017b; Zhang & Luck, 2009; 2011 for some discussions).…”

Objectives: Reduction in the amount of information (storage capacity) retained in working memory (WM) has been associated with sleep loss. The present study examined whether reduced WM capacity was also related to poor everyday sleep quality, and more importantly, whether the effects of sleep quality could be dissociated from the effects of depressed mood and age on WM. Methods: In two studies, WM was assessed using a short-term recall task, producing behavioral measures for both the amount of retained WM information (capacity) and how precise the retained WM representations were (precision). Self-report measures of sleep quality and depressed mood were obtained using questionnaires. Results: In a college-student sample, Study 1 found that poor sleep quality and depressed mood could independently predict reduced WM capacity, but not WM precision. Study 2 generalized these sleep and mood related WM capacity effects to a community sample (aged 21 to 77 years old), and further showed that age was associated with reduced WM precision. Conclusions: Together, these findings have demonstrated dissociable effects of three health-related factors (sleep, mood, and age) on WM representations and highlighted the importance of assessing different aspects of WM representations (e.g., capacity and precision) in future neuropsychological research.

Sleep Deprivation Accelerates Delay-Related Loss of Visual Short-Term Memories Without Affecting Precision

Abstract: Visual short-term memory is compromised during sleep deprivation, an effect compounded by delay. However, when memories are retrieved, they tend to be intact.
