Potential similarities in gut microbiota composition between autism spectrum disorder and neurotypical siblings: Insights from a comprehensive meta-analysis.

Background: Previous studies have explored the differences in gut microbiota (GM) between individuals with autism spectrum disorder (ASD) and neurotypical controls. However, factors such as diet, lifestyle, and environmental exposure influence GM, leading to significant variability, even among neurotypical individuals. Comparing the GM of ASD individuals with neurotypical siblings, who share similar genes and living conditions, may offer better insights into the GM mechanisms associated with ASD.

Relationship between mindfulness and self-control in deaf individuals: mediating role of inner peace and moderating role of life experience.

Background: Self-control is essential for individual health and well-being. The relationship between mindfulness and self-control has recently become a central focus of research. However, the dynamics of this relationship in deaf and hearing individuals remain underexplored.

Changes in Hippocampus and Amygdala Volume with Hypoxic Stress Related to Cardiorespiratory Fitness under a High-Altitude Environment.

The morphology of the hippocampus and amygdala can be significantly affected by a long-term hypoxia-induced inflammatory response. Cardiorespiratory fitness (CRF) has a significant effect on the neuroplasticity of the hippocampus and amygdala by countering inflammation. However, the role of CRF is still largely unclear at high altitudes.

Oxygen Metabolism-induced Stress Response Underlies Heart-brain Interaction Governing Human Consciousness-breaking and Attention.

Neuroscientists have emphasized visceral influences on consciousness and attention, but the potential neurophysiological pathways remain under exploration. Here, we found two neurophysiological pathways of heart-brain interaction based on the relationship between oxygen-transport by red blood cells (RBCs) and consciousness/attention. To this end, we collected a dataset based on the routine physical examination, the breaking continuous flash suppression (b-CFS) paradigm, and an attention network test (ANT) in 140 immigrants under the hypoxic Tibetan environment.

Approximate Number Sense in Students With Severe Hearing Loss: A Modality-Neutral Cognitive Ability.

The Approximate Number System (ANS) allows humans and non-human animals to estimate large quantities without counting. It is most commonly studied in visual contexts (i.e.

[Long-term exposure to high altitude affects spatial working memory in migrants-evidence from time and frequency domain analysis].

Long-term exposure to high altitude affects spatial working memory. Previous studies have focused on the analysis of electroencephalogram (EEG) components in time domain rather than in frequency domain. To explore the influence of long-term high altitude exposure on time dynamic characteristics and neural oscillation process of the spatial working memory, n-back task combined with the technology of event related potential recording was performed on 20 young migrants who grew at low altitude before the age of 18 and moved to high altitude more than three years ago, and 21 young people who had never been to the high altitude.
