Non-communicable diseases are multifactorial in that they can be caused by genetic factors, age, sex and poor lifestyle choices. They estimated to account for 71% of deaths globally with 80% these occurring low- middle-income countries. This is particularly true Intervertebral Disc Degeneration associated mitochondrial dysfunction. Interestingly, dysfunction arise from mutations both the nuclear genomes. The present study, therefore, aimed determine if there an association between DNA disc...
Sleep following learning facilitates the consolidation of memories. This effect has often been attributed to sleep-specific factors, such as presence sleep spindles or slow waves in electroencephalogram (EEG). However, recent studies suggest that simply resting quietly while awake could confer a similar memory benefit. In current study, we examined effects sleep, quiet rest, and active wakefulness on declarative procedural memory. We hypothesized eyes-closed rest would both benefit compared...
Abstract Traditionally, neuroscience and psychology have studied the human brain during periods of “online” attention to environment, while participants actively engage in processing sensory stimuli. However, emerging evidence shows that waking also intermittently enters an “offline” state, which is inhibited our shifts inward. In fact, humans may spend up half their hours offline [Wamsley, E. J., & Summer, T. Spontaneous entry into state wakefulness: A mechanism memory consolidation?...
Abstract Humans continuously alternate between online attention to the current environment and offline internally generated thought imagery. This may be a fundamental feature of waking brain, but remains poorly understood. Here, we took data-driven approach defining states wakefulness, using machine learning methods applied measures sensory responsiveness, subjective report, electroencephalogram (EEG), pupil diameter. We tested effect cognitive load on structure prevalence states,...
Magneto/electroencephalography (M/EEG) studies of dreaming are an essential paradigm in the investigation neurocognitive processes human consciousness during sleep, but they limited by number observations that can be collected per study. Dream research also involves substantial methodological and conceptual variability, which poses problems for integration results. To address these issues, here we present DREAM database—an expanding collection standardized datasets on sleep M/EEG combined...
Recent studies demonstrate that eyes-closed rest benefits memory consolidation, perhaps due to reduced attention environmental stimuli. Here, we asked whether focusing internal thoughts and feelings after learning similarly blocks consolidation. Verbal was tested following an consolidation period filled with either focused breath or quiet rest. Although breath-focus did not impair relative overall, participants who reported being more successful in maintaining during this condition showed...
Traditionally, neuroscience and psychology have studied the human brain during periods of “online” attention to environment, while participants actively engage in processing sensory stimuli. But emerging evidence shows that waking also intermittently enters an “offline” state, which is inhibited our shifts inward. In fact, humans may spend up half their hours offline (Killingsworth & Gilbert, 2010; Wamsley Summer, 2020). The function alternating between online forms wakefulness...
<title>Abstract</title> Mitochondrial dysfunction and impaired oxidative phosphorylation play a crucial role in the pathogenesis of various non-communicable degenerative diseases. Research indicates that these abnormalities are contributed to by genetic interindividual variability system-wide metabolic dysfunction. The objective this article was, thus, generate biochemical pipeline for single nucleotide polymorphisms (SNVs) associated with general mitochondrial use studies researching...
Humans continuously alternate between online attention to the current environment and offline internally generated thought imagery. This may be fundamental feature of waking brain, but remains poorly understood. Here, we took a data-driven approach defining states wakefulness, using machine learning methods applied measures sensory responsiveness, subjective report, EEG, pupil diameter. We tested effect cognitive load on structure prevalence states, hypothesizing that time spent would...
Abstract Introduction Past research has demonstrated that sleep benefits the consolidation of memories. However, more recent studies have suggested quiet rest could similar for memory. Here, we examined effect a brief period sleep, rest, or active wakefulness on declarative and procedural We hypothesized would equally benefit memory, compared to wakefulness. Methods After completing (Icelandic-English word pairs) memory task (the Motor Sequence Task (MST)), participants began 30-min...
Abstract Introduction Slow wave sleep (SWS) is thought to especially benefit declarative memory (i.e., for facts and events). As such, recent studies have used various methods experimentally increase the amount of slow that participants obtain, with goal assessing how SWS affects consolidation. Studies dating back decades reported exercising before may time spent in SWS. Thus, aim current project was determine whether after learning verbal information enhances during a subsequent nap and/or...
