Summary: Sleep plays a crucial role in memory consolidation, as information is reactivated, transferred, and redistributed during sleep. This study shows that using a particular odor during learning and reactivating the memory during sleep can enhance the consolidation of complex information.

Summary: This study found that language learning involves different memory systems in the early and late stages, with early SLL relying on declarative memory and late SLL shifting to procedural memory. Increases in sleep spindle characteristics were associated with early SLL, while increases in REM activity were associated with late SLL.

Summary: The study provides evidence that long-term memory and working memory in humans are supported by different offline neural mechanisms that compete for resources during sleep, leading to a behavioral trade-off. This suggests the presence of a sleep switch mechanism that toggles between different memory processing during sleep.

Summary: The study found that there was no significant correlation between the amount of slow-wave sleep (SWS) and memory benefits mediated by sleep at an individual level. However, subjective sleep quality ratings were significantly associated with the amount of SWS.

Summary: Sleep significantly improves the consolidation of factual knowledge, but does not enhance relearning. After 1 week, there is still a numerical memory advantage for the sleep group, though it is no longer statistically significant.

Summary: This study investigated the effects of menstrual cycle phases and oral contraceptive use on cardiorespiratory responses during exercise in women. The results showed that certain phases of the menstrual cycle and oral contraceptive cycle could lead to increased ventilatory parameters, indicating lower cardiorespiratory efficiency. However, these differences had limited clinical significance, and the impact of the menstrual cycle on submaximal exercise was minimal.

Summary: This review discusses the potential of using psychoactive drugs to manipulate sleep spindles and their effects on memory. Most studies suggest that benzodiazepines and Z-drugs can enhance sleep spindle activity, but the translation to improved memory needs further investigation.

Summary: The study found that individuals with OSAS have significantly lower spindle density in N3 and shorter spindle duration in N2 compared to healthy controls. Furthermore, individuals with mild OSAS showed sleep spindle characteristics more similar to healthy controls, unlike those with moderate and severe OSAS.

Summary: Children can easily link new words to unnamed objects through fast mapping, but their memory for these words may be poor without memory supports like further exposure or sleep. Napping after fast mapping has been shown to improve retention of novel words in young children, suggesting that memory supports can enhance retention and stability of word-object mappings over time.

Summary: Sleep abnormalities, specifically reductions in sleep spindles, are early features of schizophrenia, with deficits in brain connectivity and cognitive function. This study examined sleep spindle density (SSD) differences in SZ, FEP, and FHR populations compared to healthy controls through a meta-analysis. Results showed a large effect size for SSD in patients, with illness duration significantly associated with SSD. Further research will explore the potential of SSD as a predictor for SZ or therapeutic intervention.

Summary: This study investigated the memory of nonadjacent dependencies in 6-8 month old infants and examined whether sleep after learning affects this memory. The results showed that infants were able to retain memory of nonadjacent dependencies regardless of whether they napped or stayed awake. However, napping did affect a specific processing stage, suggesting that memory evolves during sleep.

Summary: The effects of TMR on task performance can last for at least 10 days post-encoding, with time spent in stage 2 of NREM sleep predicting cueing benefit. In addition, there is a significant increase in spindle density and SO-spindle coupling during the cue period, highlighting their importance in procedural memory consolidation.

Summary: Endogenous ovarian hormones may increase the risk of binge eating in females through gene x hormone interactions and hormonally induced increases in genetic influences. Combined oral contraceptives (COCs), which mimic the riskiest hormonal environment for binge eating, are commonly used by women. Preliminary studies suggest that COCs may increase the risk of binge eating and related phenotypes, especially in genetically vulnerable women. Larger and more systematic studies are needed to explore the relationship between COCs and binge eating, with the goal of advancing personalized medicine.

Summary: This study investigated the impact of novel stimuli on the left and right medial temporal lobes, revealing different activations in response to novel designs of different usefulness. The findings suggest that the left medial temporal lobe is predominantly involved in usefulness processing, while the right medial temporal lobe is predominantly involved in novelty processing. Additionally, the left parahippocampal gyrus showed stronger connectivity with the anterior cingulate cortex when responding to novel useless designs, while the right parahippocampal gyrus showed stronger connectivity with the amygdala, midbrain, and hippocampus.

Summary: Many pregnant women experience impairments in attentional capacities. This study found that pregnant women had increased alpha frequency and a greater magnitude of alpha ERD prior to target-onset, which correlated with improved accuracy in a visuo-spatial attention task. Estradiol levels also showed a negative correlation with accuracy in pregnant women.

Summary: The power spectra of sleep electroencephalograms (EEG) consist of both a decaying power-law and spectral peaks. Traditional methods ignore this structure and may misrepresent the EEG spectra. The FOOOF method was used to separate and parameterize the components, revealing sleep stage sensitivity and potential indicators of sleep states.

Summary: The neuroscience of hormonal contraceptives is a crucial yet emerging field. Although limited in size and scope, existing studies emphasize the complex effects of hormonal contraceptives on the nervous system, which can vary due to individual differences, contraceptive type and formulation, and timing of use. Neuroscientists can provide individuals with knowledge about the biopsychological effects of hormonal contraceptives through rigorous randomized controlled trials, large-scale studies examining population-level trends, and dense imaging or intensive longitudinal studies assessing individual-level effects.

Summary: Due to the demands of competitive sports, the sleep of adolescent athletes may be influenced by their training. There is no clear evidence on how training characteristics affect sleep quality and quantity. A study conducted on Austrian soccer players found that higher training intensity increases wake time, later training leads to longer sleep duration, and one training session per day is best for sleep quality. Somatic complaints and individual training loads should be considered in training schedules, and the use of ECG data for sleep analysis in athletes shows promise.

Summary: This review provides a comprehensive overview of the history of sleep learning research conducted in humans, synthesizing the findings from 51 research papers. The results suggest that simpler forms of learning, such as habituation and conditioning, may be possible during sleep, while the findings for more complex, applied learning are more divergent. Behavioral evidence for the transfer of new knowledge to wake remains inconclusive, although neural markers often indicate processing and learning during sleep.

Summary: This survey examines the implementation, attitudes, skills, and suggestions for improvement of evidence-based practice (EBP) among sports psychologists in the German-speaking countries (D-A-CH). The results indicate that participants have positive attitudes towards EBP and possess higher skills in sharing and applying EBP. However, they perceive their own implementation and techniques for retrieving and reviewing evidence as areas for improvement. Lack of time is identified as a possible reason for low implementation. Practitioners suggest improved access to current literature, intervision groups, clear guidelines, and more practice-based research to better integrate EBP into their practice.
