The father's genes drive a fetus' demand for larger blood vessels and more nutrients, while maternal genes in the placenta try to take control over how much nourishment the mother provides.
A new mathematical model explains how the brain has the ability to continuously acquire new skills, specifically movement-based skills, without forgetting or degrading old ones. The theory, dubbed COIN, suggests identifying current context is key to learning how to move our bodies when acquiring skills.
New findings contradict the existing thought that Alzheimer's starts from a single point in the brain and causes a chain reaction that leads to cell death. Instead, a new study reports, Alzheimer's disease reaches different brain regions early on. The speed by which the disease kills brain cells in these regions directly impacts the progression of Alzheimer's.
A new mathematical model is able to predict the optimal exercise regime to help build muscles.
Two newly developed tests, one which analyzes urine samples and a simple blood test, can detect the presence of glioma brain cancer.
Reconstituting the amount of chondroitin 6-sulphate to perineuronal nets completely restored memory and brain plasticity in aging mice to a similar level as seen in younger animals, a new study reports. The findings could lead to new therapies to restore age-related memory loss in older humans.
A newly developed questionnaire can detect autism in children between the ages of 18 to 30 months.
A new study reveals the impact climate played in the evolution of the human brain and body. Studying 300 fossils from the genus Homo found across the globe, researchers found those who lived in colder climates had larger body frames. Larger bodies provided a buffer from colder temperatures. Brain size tended to be larger in those who lived in environments with less vegetation and survived by hunting large animals, a task that involved higher cognitive function.
While those with autism are less likely to use substances than those who are not on the autism spectrum, those who do are more likely to self-medicate for their mental health symptoms. Those with ASD who self-medicate report they do so to improve focus and attention and, in some cases, to mask ASD symptoms.
Switching off activity in the anterior cingulate cortex prevented marmoset monkeys from making an association between behavior and a particular outcome.
Activity in the dorsal mid insular could drive different interpretations in bodily sensations in those with mental health disorders like depression, anorexia, and panic disorders.
Experiencing bullying and aggression as a teen or young adult increases violent ideations, including thoughts of harming or killing others, a new study reports.
