Summary: A new study utilizing UK Biobank data has unveiled the genetic roots of left-handedness, pinpointing rare variants in the beta-tubulin gene TUBB4B significantly associated with this trait. These findings not only shed light on the complex interplay between genetics and brain asymmetry but also link left-handedness with neurodevelopmental […]

Summary: Disturbances in gut flora during infancy are linked to the later development of neurodevelopmental disorders like autism and ADHD. Analyzing over 16,000 children from the ABIS study, researchers identified significant biomarkers in cord blood and stool samples that correlate with future diagnoses of these disorders. The study highlights […]

Summary: Researchers reviewed 50 studies to deepen our understanding of aphantasia, a phenomenon where individuals can’t visualize mentally. The research reveals aphantasia’s diverse impact, from reduced autobiographical memory and face recognition to broader implications in music imagination and occupation choices, suggesting a spectrum rather than a binary condition. Additionally, […]

Summary: Certain household chemicals, including those found in personal-care products and furniture, pose a risk to brain health, potentially contributing to diseases like multiple sclerosis and autism. The study reveals that these chemicals damage oligodendrocytes, essential cells for nerve cell protection. Key findings include the identification of harmful organophosphate […]
Brain Abnormalities in Children with Developmental Language Disorder
Summary: Researchers have discovered that the anterior neostriatum, a part of the brain linked with movement, shows abnormalities in children with developmental language impairments. This study utilized a novel computational approach to analyze data from 22 studies, revealing that these abnormalities are uniquely prevalent in the anterior neostriatum. The […]

Summary: People with autism experience pain at a higher intensity than those not on the autism spectrum and are less adaptable to the sensation. This revelation contradicts the prevailing belief that those with ASD tend to be indifferent to pain. Source: Tel Aviv University A new study has examined […]
Community Newsletter: Better measurement; Rett rescue; interactomes; social touch
We’re kicking things off this week with a PsyArXiv preprint about ways to improve measurement precision in neuroscience — and enhance reproducibility. Significance statement: Huge samples are not the only answer to the replication crisis. Additionally, we should make our measurements more precise. In this primer, we tell you […]
Fresh Questions About Oxytocin as the ‘Love Hormone’ Behind Pair Bonding
Summary: The “love hormone” oxytocin may not play as critical a role in bonding as previously believed. Removing the oxytocin receptor in animal models still resulted in monogamous mating, attachment, and parental bonding behaviors, although females without the receptor produced milk in smaller quantities. Findings reveal parenting and bonding […]
