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 new study found a person's math ability was linked to levels of GABA and glutamate in the brain. In children, greater math fluency was associated with higher GABA levels in the left intraparietal sulcus, while lower levels of GABA were linked to math ability in adults. The reverse was true for glutamate in both children and adults.
People who practice meditation often report feeling "pure awareness" in which they say they experience consciousness itself. The state encompasses specific sensations and non-specific feelings, thoughts, and perceptions. Researchers say their findings will help explain "pure consciousness," and work to generate a prototypical minimal model for human conscious perception.
Contrary to popular belief, moderate coffee consumption does not increase the risk of cardiac arrhythmias or other heart health problems. Researchers found daily coffee consumption was associated with a 3% lower risk of certain cardiac conditions. Findings add to the growing body of evidence that coffee consumption can help reduce the risk of several health problems including Parkinson's disease and some cancers.
People who are genetically predisposed to be "early birds" only take a few days to adjust to time changes as a result of daylight savings. Night owls can take over a week to adjust to the time change.
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.
1 in 20 children hospitalized for COVID-19 in the UK develop neurological complications associated with the viral infection. A new study reveals a wide spectrum of neurological complications in children and suggests they may be more common than in adults admitted to hospital with COVID.
