‘Grey skies are gonna clear up, put on a happy face’

Just like the famous lyrics suggest, if you put on a happy face you will feel a little brighter, according to a new study.

Engineers light the way to nerve-operated prosthetics of the future

A multi-disciplinary team has found a way to convert nerve impulses into light, opening the way for more scalable neural implants.

Here’s how the brain works when we choose to help someone in danger

How do people decide whether to intervene and help others in danger? Researchers now show that the same system in the brain that enables us to avoid danger is also activated during selfless, helping behavior.

Word and face recognition can be adequately supported with half a brain

An unprecedented study of brain plasticity and visual perception found that people who, as children, had undergone surgery removing half of their brain correctly recognized differences between pairs of words or faces more than 80% of the time. Consider…

New study expands range of potential Alzheimer’s drugs

Alzheimer’s disease is associated with a reduction of insulin receptors in brain microvessels, which may contribute to brain insulin resistance and the formation of amyloid plaques, one of the disease’s hallmarks. The findings could affect the search f…

Study looks inside the brain during sleep to show how memory is stored

A new study looks deep inside the brain, where previous learning was reactivated during sleep, resulting in improved memory. Neuroscientists teamed up with clinicians to study the brain electrical activity in five of the center’s patients in response t…

Young child’s brain, not age, determines nap transitions, research suggests

Why do some 4- and 5-year-olds still nap like clockwork every afternoon, while other preschoolers start giving up habitual napping at age 3? It’s a question many parents no doubt ponder and one that a sleep scientist has been considering for years. Now…

During sleep, one brain region teaches another, converting novel data into enduring memories

Using a neural network model, neuroscientists have found that, as the brain moves between REM and slow-wave sleep cycles, the hippocampus teaches the neocortex what it learned. This process seems to convert novel, fleeting data into enduring memories.

Researchers confirm stress link in the brain

Researchers have confirmed a pathway in the brain that governs how animals, including humans, respond to stress. The findings could yield better understanding of the physical- and mental-health impacts of chronic stress in humans.

‘That just sounds wrong’ — New study shows how our brains tell us when a sound is off

Whether it’s a car door not properly closed, a shanked kick in football, or a misplaced note in music, our ears tell us when something doesn’t sound right. A team of neuroscientists has recently uncovered how the brain works to make distinctions betwee…
