Designer cytokine makes paralyzed mice walk again

To date, paralysis resulting from spinal cord damage has been irreparable. With a new therapeutic approach, scientists from the Department for Cell Physiology at Ruhr-Universität Bochum (RUB) headed by Professor Dietmar ...

T cells linked to myelin implicated in MS-like disease in monkeys

Scientists have uncovered new clues implicating a type of herpes virus as the cause of a central nervous system disease in monkeys that's similar to multiple sclerosis in people.

Study measures brain volume differences in people with HIV

Nearly 38 million people around the world are living with HIV, which, with access to treatment, has become a lifelong chronic condition. Understanding how infection changes the brain, especially in the context of aging, is ...

Study reveals the relaxing music to help you sleep

Perhaps there's nothing quite as frustrating as trying and failing to fall asleep. But if you're one of the many people who struggle to switch off come bedtime, the findings of a new study might give you some hope—and the ...

How the brain paralyzes you while you sleep

We laugh when we see Homer Simpson falling asleep while driving, while in church, and even while operating the Springfield nuclear reactor. In reality though, narcolepsy, cataplexy and rapid eye movement (REM) sleep behavior ...

Cochlear implants aid speech recognition in most adults

(HealthDay)—Most adult patients have statistically significant postoperative improvements in speech recognition after receiving cochlear implants, according to a study published online Jan. 7 in JAMA Otolaryngology-Head ...

Disagreeing takes up a lot of brain real estate

Yale researchers have devised a way to peer into the brains of two people simultaneously while are engaged in discussion. What they found will not surprise anyone who has found themselves arguing about politics or social ...

Neuroscience

Study suggests compound protects myelin, nerve fibers

A compound developed at Oregon Health & Science University appears to protect nerve fibers and the fatty sheath, called myelin, that covers nerve cells in the brain and spinal cord.

Neuroscience

Tapping the brain to boost stroke rehabilitation

Stroke survivors who had ceased to benefit from conventional rehabilitation gained clinically significant arm movement and control by using an external robotic device powered by the patients' own brains.

Neuroscience

Master designers: Architects of the brain revealed

Brain cells often cluster and grow together creating three-dimensional columns. While this pillar-like pattern of neurons is established, the exact mechanism behind its formation is still elusive. Makoto Sato's team at Kanazawa ...

Advances in understanding autism, based on "mosaic" mutations

Two studies in today's Nature Neuroscience, led by researchers at Boston Children's Hospital, Brigham and Women's Hospital (BWH), and Harvard Medical School (HMS), implicate mosaic mutations arising during embryonic development ...

Neuroscience

Which came first, sleep or the brain?

Stay awake too long, and thinking straight can become extremely difficult. Thankfully, a few winks of sleep is often enough to get our brains functioning up to speed again. But just when and why did animals start to require ...

Neuroscience

Scientists paint multi-color atlas of the brain

The human brain contains approximately 86 billion neurons, or nerve cells, woven together by an estimated 100 trillion connections, or synapses. Each cell has a role that helps us to move muscles, process our environment, ...

Neuroscience

Mapping a life's worth of changes in a mysterious brain structure

Until recently, scientists didn't know much about perivascular spaces (PVS), fluid-filled regions in the brain involved in clearing waste and toxins—mainly because it's tough to get a clear look at them using neuroimaging. ...

Neuroscience

Perceiving prosthesis as lighter thanks to neurofeedback

Transmitting sensory signals from prostheses to the nervous system helps leg amputees to perceive prosthesis as part of their body. While amputees generally perceive their prostheses as heavy, this feedback helps them to ...

Neuroscience

Study shows people hear what they expect to hear

Humans depend on their senses to perceive the world, themselves and each other. Despite senses being the only window to the outside world, people do rarely question how faithfully they represent the external physical reality. ...
