“…Importantly, limited evidence has also suggested that SD disrupts hippocampus-dependent spatial memory in humans ( Ferrara et al., 2008 ; Peng et al., 2020 ). Moreover, clinical observations have documented that patients who suffer from a clinical sleep disorder often exhibit spatial memory deficits.…”

Spatial memory is a brain function involved in multiple behaviors such as planning a route or recalling an object's location. The formation of spatial memory relies on the homeostasis of various biological systems, including healthy sleep and a well-functioning immune system. While sleep is thought to promote the stabilization and storage of spatial memories, considerable evidence shows that the immune system modulates neuronal processes underlying spatial memory such as hippocampal neuroplasticity, long-term potentiation, and neurogenesis. Conversely, when sleep is disturbed and/or states of heightened immune activation occur, hippocampal regulatory pathways are altered, which – on a behavioral level - may result in spatial memory impairments. In this Brief Review , I summarize how sleep and the immune system contribute to spatial memory processes. In addition, I present emerging evidence suggesting that sleep disturbance and inflammation might jointly impair spatial memory. Finally, potentials of integrated strategies that target sleep disturbance and inflammation to possibly mitigate risk for spatial memory impairment are discussed.

“…The P3 amplitude increased with task difficulty and was larger in table tennis players than in the controls. The P3 component reflects the deployment of attentional resources, and the P3 amplitude reflects an individual’s ability to distinguish and evaluate target stimuli [ 19 ]. Long-term special training can help table tennis players actively adapt to fast, complex, and changeable situations.…”

Spatial cognition facilitates the successful completion of specific cognitive tasks through lateral processing and neuroplasticity. Long-term training in table tennis induces neural processing efficiency in the visuospatial cognitive processing cortex of athletes. However, the lateralization characteristics and neural mechanisms of visual–spatial cognitive processing in table tennis players in non-sport domains are unclear. This study utilized event-related potentials to investigate differences in the spatial cognition abilities of regular college students (controls) and table tennis players. A total of 48 participants (28 controls; 20 s-level national table tennis players) completed spatial cognitive tasks while electroencephalography data were recorded. Task performance was better in the table tennis group than in the control group (reaction time: P < 0.001; correct number/sec: P = 0.043), P3 amplitude was greater in the table tennis group (P = 0.040), spatial cognition showed obvious lateralization characteristics (P < 0.001), table tennis players showed a more obvious right-hemisphere advantage, and the P3 amplitude in the right hemisphere was significantly greater in table tennis athletes than in the control group. (P = 0.044). Our findings demonstrate a right-hemisphere advantage in spatial cognition. Long-term training strengthened the visual–spatial processing ability of table tennis players, and this advantage effect was reflected in the neuroplasticity of the right hemisphere (the dominant hemisphere for spatial processing).

“…[ 8 , 9 ] Working memory is an important component of cognitive neuroscience research [ 10 , 11 ] and includes form-specific information storage systems comprising a phonological loop that processes verbal information, a visuospatial sketchpad for processing spatial information, and a central executive system consisting of 3 cognitive processes (inhibition, shifting, and updating). [ 12 ] Peng [ 13 ] in their study found that sleep insufficiency impaired the working memory ability of college students.…”

“…Studies have shown that exposure to high altitudes can easily lead to sleep insufficiency, [ 6 ] which can impair individual working memory. [ 13 ] However, individuals may have different sleep performances and processing patterns of spatial working memory in low-pressure and hypoxic environments. Therefore, we decided to use the spatial 2-back paradigm and combined ERP technology with it to investigate the effects of sleep insufficiency on spatial working memory under low-pressure and low-oxygen environments.…”

Background: This study aimed to investigate the effects of sleep insufficiency on spatial working memory in low-pressure and hypoxic environments. Methods: We selected 58 insufficient sleepers and 27 normal sleepers among the college students living in high-altitude areas for a long time to receive a spatial 2-back working memory task, while collecting behavioral and electroencephalograph data. We adopted an independent sample t-test and repeated measures analysis of variance to compare the differences in response time and accuracy, P2 and late positive potential components, and theta band energy values in the spatial working memory task between insufficient and normal sleepers. Results: We found no significant differences in response time and accuracy between the insufficient sleep group and the normal sleep group; however, the P2 peak value and the early theta band energy value were higher in the insufficient sleep group than in the normal sleep group. Conclusions: These results suggest that the spatial working memory ability of individuals with sleep insufficiency was weakened under low-pressure and low-oxygen environment.
