Recovery Sleep Attenuates Impairments in Working Memory Following Total Sleep Deprivation

Abstract Background: Considering the well-known detrimental effects of sleep deprivation (SD) on cognitive function and quality of life, sleep disturbances represent a major physical and mental health issue. Because working memory plays an important role in many complex cognitive processes, it is necessary to identify strategies that can effectively counteract the negative effects of SD on working memory. Methods: In the present study, we utilized event-related potentials (ERPs) to investigate the restorative effect of 8 h of recovery sleep (RS) on working memory impairments induced by 36 h of total sleep deprivation (TSD). We analyzed data from 16 healthy male participants. All participants completed a 2-back working memory task before and after 36 h of TSD and after 8 h of RS. Electroencephalography (EEG) data were recorded during the task. Results: N2 and P3 components related to working memory exhibited low-amplitude slow-wave characteristics following 36 h of TSD. Significant decreases in the latency of the N2 component were observed after 8 h of RS. RS also induced significant increases in the amplitude of the P3 component, along with significant decreases in P3 latency. Conclusions: Eight hours of RS also attenuated decreases in working memory performance caused by 36 h of TSD. However, the effects of RS appear to be limited.

Neuroticism is a personality trait associated with impaired attention, memory, and error detection. Thus, the present study investigated the visual N100 and P200 event-related potentials components associated with attention using a 2-back working memory task in healthy neurotic and nonneurotic participants, evaluated using the Neuroticism, Extraversion, Openness Five Factor Inventory. A total of 35 healthy participants were asked to perform the 2-back task while recording electroencephalographic activity from 64 electrodes on the scalp. Analysis of the N100 and P200 amplitude and latency in high neuroticism and low neuroticism subjects showed an increased P200 amplitude and latency for high neuroticism subjects in the frontal and parietal regions, respectively. However, there were no significant performance differences between the high and low neuroticism subjects for the 2-back working memory task. Therefore, the results suggest that neuroticism is associated with the P200 component elicited in the context of a working memory task.

Negative Stimuli

Abstract Introduction Stimuli with an emotional valence tend to produce better recognition from memory than neutral stimuli. Sleep loss is believed to increase reactivity to negative stimuli, as compared to positive stimuli, which may comparatively enhance subsequent recognition from memory for negative stimuli. We investigated the impact of total sleep deprivation (TSD) on recognition accuracy for words with different emotional valence using the Affective Item Source Memory Task (AISM). Methods N=14 adults (ages 21–39; 7 females) completed a 4-day in-laboratory study with 9h baseline sleep (22:00-07:00), 39h acute TSD, and 9h recovery sleep. The AISM was administered at 16:30 during baseline and after 34h TSD. During a 5min study phase, participants heard a list, twice, of 20 positive, 20 negative, and 20 neutral words spoken with a male or female voice. During an immediately subsequent 8min recognition phase, participants heard 120 words (50% new) and judged whether each word had been presented in the study list (item memory). For words judged to have been presented previously, participants indicated whether those were presented by a female or male speaker (source memory). Results Mixed-effects ANOVA showed effects of session (p<0.001) and valence (p<0.001) on item memory. At baseline, accuracy was greatest for neutral and positive words compared to negative words. During TSD, accuracy declined for all three valences, and no interaction of session by valence was detected. No effects of TSD or valence on source memory were observed. Conclusion Sleep deprivation reduced item memory for words of all valence types. However, there was no comparatively greater impact on item or source memory for negative words nor any differential effect of TSD for different valences. Whether our results would hold with longer time intervals between task phases or an intervening sleep period remains to be determined. Support Jazz Pharmaceuticals

We study the cognitive processing of visual working memory in three different conditions of memory load and configuration change. Altering this features has been shown to alter the brain’s processing in memory tasks. Most studies dealing with this issue have used the verbal-phonological modality. We use complex geometric polygons to assess visual working memory in a modified change detection task. Three different types of backgrounds were used to manipulate memory loading and 18 complex geometric polygons to manipulate stimuli configuration. The goal of our study was to test whether the memory load and configuration affect the correct-recall ratios. We expected that increasing visual items loading and changing configuration of items would induce differences in working memory performance. Brain activity related to the task was assessed through event-related potentials (ERP), during the test phase of each trial. Our results showed that visual items loading and changing of item configuration affect working memory on test phase on ERP component P2, but does not affect performance. However frontal related ERP component—P3—was minimally affected by visual memory loading or configuration changing, supporting that working memory is related to a filtering processing in posterior brain regions.

Multichannel Recordings

We investigated the hypothesis that the covert focusing of spatial attention mediates the on-line maintenance of location information in spatial working memory. During the delay period of a spatial working-memory task, behaviorally irrelevant probe stimuli were flashed at both memorized and nonmemorized locations. Multichannel recordings of event-related potentials (ERPs) were used to assess visual processing of the probes at the different locations. Consistent with the hypothesis of attention-based rehearsal, early ERP components were enlarged in response to probes that appeared at memorized locations. These visual modulations were similar in latency and topography to those observed after explicit manipulations of spatial selective attention in a parallel experimental condition that employed an identical stimulus display.
