Brains memory center needed to recognize image sequences but not single sights

A new MIT study of how a mammalian brain remembers what it sees shows that while individual images are stored in the visual cortex, the ability to recognize a sequence of sights critically depends on guidance from the hippocampus, a deeper structure strongly associated with memory but shrouded in mystery about exactly how. By suggesting that the hippocampus isn’t needed […]

Children who are physically fitter have bigger brains, new study finds

Children with a higher level of physical fitness have larger brains, and both aerobic capacity and strength/speed are related to the amount of gray and white matter in the brain, meaning that overweight or obese children are adversely affected. Furthermore, a greater amount of white matter in the brain is linked to superior cognitive performance. These are the findings derived […]

Mediterranean diet could keep aging brains sharp

(HealthDay)—Helping your brain stay sharp with age may be as simple as changing up the food on your plate at dinnertime, a new study suggests. The study focused on the healthy “Mediterranean” diet, a regimen reliant on olive oil, beans, nuts, fruits, vegetables and whole grains, with chicken and fish largely replacing red meat. Dairy products and eggs are only […]

Here's what living under the threat of extinction is doing to our brains

Feelings of anxiety and dread over climate change are not uncommon and as global warming continues to worsen, the toll that it’s taking on our mind is likely getting worse too. From the ongoing pandemic to the atomic fear associated with the Cold War and the Cuban Missile Crisis, modern humanity is no stranger to living under the threat of […]

Modern maker trend could jumpstart aging brains

Frustrated that her sweater got lost in the community laundry, 92-year-old Gigi took advantage of an embroidery machine to label two others. Jewelry lover Betty had been reluctant to wear her fine necklaces, fearful they would get tangled in the tubes of her oxygen mask, so the 96-year-old found a pattern and 3-D-printed a heart-shaped pendant. Esther announced one day […]

Brains of blind people adapt to sharpen sense of hearing, study shows

Research has shown that people who are born blind or become blind early in life often have a more nuanced sense of hearing, especially when it comes to musical abilities and tracking moving objects in space (imagine crossing a busy road using sound alone). For decades scientists have wondered what changes in the brain might underlie these enhanced auditory abilities. […]

Alzheimer’s disease could be treated by zapping patients’ brains

Alzheimer’s disease could be treated by zapping the brains of older people with electricity for just 25 minutes as study proves it can boost the memory of over-60s It takes only a weak electrical current to restore thinking powers, experts say The tiny pulses of electricity are thought to synchronise their brainwaves  Older people zapped performed as well as those […]

Smoking, high blood pressure, diabetes and obesity each linked to unhealthy brains

Factors that influence the health of our blood vessels, such as smoking, high blood and pulse pressures, obesity and diabetes, are linked to less healthy brains, according to research published in the European Heart Journal today. The study examined the associations between seven vascular risk factors and differences in the structures of parts of the brain. The strongest links were […]

General anesthesia is unlikely to have lasting effects on the developing brains of young children: study

A single hour of general anaesthesia in early infancy—longer than is necessary to perform the most common types of minor surgeries in childhood—does not result in measurable neurodevelopmental or behavioural problems up to the age of 5 years, according to the first randomised trial of its kind involving 722 infants in seven countries, published in The Lancet. The trial provides […]
