Can deep sleep help devastating brain disorders? Scientists studying Parkinson's want to find out

Sleep may be one of the most potent medicines for the brain, scientists are discovering, as they explore the inner labyrinths of the three-pound organ during deep sleep and dream cycles in both health and disease.

Genetics

Researchers use brain organoids to identify origin of neurodevelopmental disorder

With the help of cerebral organoids, IMBA scientists were able to ascertain that tuberous sclerosis, a rare neurodevelopmental genetic disorder, arises developmentally rather than only genetically. With these patient-derived ...

Neuroscience

Researchers identify osteoarthritis 'pain pathway'

Researchers from North Carolina State University have discovered that a particular molecular signaling pathway plays an important role in producing osteoarthritis (OA) pain. Using a mouse model of painful osteoarthritis, ...

How gut neurons communicate with the brain to control thirst

Drinking a glass of water is often sufficient to quench thirst after exercising. But while the sensation of thirst may be satiated after just a few minutes of drinking, the process of rehydration actually takes around half ...

Meat, multiple sclerosis and the microbiome

Eating more meat, having less of certain bacteria in the gut, and more of certain immune cells in the blood, all link with multiple sclerosis, reports a team of researchers led by UConn Health and Washington University School ...

Neuroscience

The link between alcohol consumption and epilepsy

Epilepsy, a common neurological disorder associated with stigma, psychiatric comorbidities, and rising healthcare costs, affects approximately 50 million people globally. A common risk factor associated with the development ...

Neuroscience

Can brain stimulation improve memory formation?

For some adults, the use of a responsive neurostimulation (RNS) system implanted in the brain can help lessen or control seizures related to certain types of epilepsy. The device works similar to a pacemaker but is implanted ...

Active ingredient in cannabis protects aging brain cells

Decades of research on medical cannabis has focused on the compounds THC and CBD in clinical applications. But less is known about the therapeutic properties of cannabinol (CBN). Now, a new study by Salk scientists shows ...

Constant tinnitus is linked to altered brain activity

There has to date been no reliable objective method of diagnosing tinnitus. Researchers from Karolinska Institutet now show that brainstem audiometry can be used to measure changes in the brain in people with constant tinnitus. ...

Genetics

Contrary to the common view, cerebral palsy can be genetic

Cerebral palsy, a non-progressing motor impairment that begins in early childhood, has widely been viewed as the result of oxygen deprivation during birth or other birth-related factors such as prematurity. While this is ...

Silencing a faulty gene may uncover clues to rare forms of ALS

Using an experimental drug, researchers have been able to suppress a mutated amyotrophic lateral sclerosis (ALS) gene. Studies in mice demonstrate that the therapy could show promise in treating rare, aggressive forms of ...

Africa's brain specialist shortfall is 'risking lives'

A critical shortfall in neurologists in Africa must be addressed in order to meet the health needs of patients with disorders that affect the brain, nerve and spinal cord, a study says.

Neuroscience

A cure for Alzheimer's is taking longer than expected; here's why

In her latest research paper, published in the Journal of Molecular Neuroscience, Anne Robinson, Head of Carnegie Mellon's Department of Chemical Engineering, explains why understanding the progression of neurodegeneration ...

Rapid eye movement sleep helps protect against predator attack

Rapid eye movement (REM) sleep brings about brief but periodic awakenings. In 1966, Dr. Frederick Snyder reported the "sentinel" function of REM could help animals prepare a fight or flight response against potential predator ...

Neuroscience

In visual memory, size matters

Every day we encounter images on the wall, in newspapers, books, and electronic devices. Some become etched in our memory and some don't. The elements influencing whether we remember one image and not the other aren't yet ...

Reinterpreting our brain's body maps

Our brain maps out our body to facilitate accurate motor control; disorders of this body map result in motor deficits. For a century, the body map has been thought to have applied to all types of motor actions. Yet scientists ...
