NREM sleep brain networks modulate cognitive recovery from sleep deprivation

Author(s): Lee K; Wang Y; Cross NE; Jegou A; Razavipour F; Pomares FB; Perrault AA; Nguyen A; Aydin Ü; Uji M; Abdallah C; Anticevic A; Frauscher B; Benali H; Dang-Vu TT; Grova C;

Decrease in cognitive performance after sleep deprivation followed by recovery after sleep suggests its key role, and especially non-rapid eye movement (NREM) sleep, in the maintenance of cognition. It remains unknown whether brain network reorganization in NREM sleep stages N2 and N3 can uniquel ...

A multidimensional investigation of sleep and biopsychosocial profiles with associated neural signatures

Author(s): Perrault AA; Kebets V; Kuek NMY; Cross NE; Tesfaye R; Pomares FB; Li J; Chee MWL; Dang-Vu TT; Yeo BTT;

Sleep is essential for optimal functioning and health. Interconnected to multiple biological, psychological and socio-environmental factors (i.e., biopsychosocial factors), the multidimensional nature of sleep is rarely capitalized on in research. Here, we deployed a data-driven approach to ident ...

A multidimensional investigation of sleep and biopsychosocialprofiles with associated neural signatures

Author(s): Perrault AA; Kebets V; Kuek NMY; Cross NE; Tesfaye R; Pomares FB; Li J; Chee MWL; Dang-Vu TT; Thomas Yeo BT;

Sleep is essential for optimal functioning and health. Interconnected to multiple biological, psychological and socio-environmental factors (i.e., biopsychosocial factors), the multidimensional nature of sleep is rarely capitalized on in research. Here, we deployed a data-driven approach to ident ...

Methodological approach to sleep state misperception in insomnia disorder: Comparison between multiple nights of actigraphy recordings and a single night of polysomnography recording

Author(s): Maltezos A; Perrault AA; Walsh NA; Phillips EM; Gong K; Tarelli L; Smith D; Cross NE; Pomares FB; Gouin JP; Dang-Vu TT;

Study objective: To provide a comprehensive assessment of sleep state misperception in insomnia disorder (INS) and good sleepers (GS) by comparing recordings performed for one night in-lab (PSG and night review) and during several nights at-home (actigraphy and sleep diaries). Methods: Fifty-sev ...

Effects of cognitive behavioral therapy for insomnia on subjective and objective measures of sleep and cognition

Author(s): Perrault AA; Pomares FB; Smith D; Cross NE; Gong K; Maltezos A; McCarthy M; Madigan E; Tarelli L; McGrath JJ; Savard J; Schwartz S; Gouin JP; Dang-Vu TT;

Study objectives: To assess the effects of Cognitive Behavioral Therapy for insomnia (CBTi) on subjective and objective measures of sleep, sleep-state misperception and cognitive performance. Methods: We performed a randomized-controlled trial with a treatment group and a wait-list control group ...

An altered balance of integrated and segregated brain activity is a marker of cognitive deficits following sleep deprivation

Author(s): Cross NE; Pomares FB; Nguyen A; Perrault AA; Jegou A; Uji M; Lee K; Razavipour F; Ali OBK; Aydin U; Benali H; Grova C; Dang-Vu TT;

Sleep deprivation (SD) leads to impairments in cognitive function. Here, we tested the hypothesis that cognitive changes in the sleep-deprived brain can be explained by information processing within and between large-scale cortical networks. We acquired functional magnetic resonance imaging (fMRI ...

Data-driven beamforming technique to attenuate ballistocardiogram artefacts in electroencephalography-functional magnetic resonance imaging without detecting cardiac pulses in electrocardiography recordings

Author(s): Uji M; Cross N; Pomares FB; Perrault AA; Jegou A; Nguyen A; Aydin U; Lina JM; Dang-Vu TT; Grova C;

Simultaneous recording of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI) is a very promising non-invasive neuroimaging technique. However, EEG data obtained from the simultaneous EEG-fMRI are strongly influenced by MRI-related artefacts, namely gradient artefacts (G ...

Cortical gradients of functional connectivity are robust to state-dependent changes following sleep deprivation.

Author(s): Cross N; Paquola C; Pomares FB; Perrault AA; Jegou A; Nguyen A; Aydin U; Bernhardt BC; Grova C; Dang-Vu TT;

Sleep deprivation leads to significant impairments in cognitive performance and changes to the interactions between large scale cortical networks, yet the hierarchical organisation of cortical activity across states is still being explored. We used functional magnetic resonance imaging to assess ...
