DARPA's HAPTIX program seeks to provide amputees with natural touch sensations. ...

Researchers have defined a sub-type of Alzheimer's disease which is relatively widespread, yet not well recognized or treated appropriately. ...

An MRI sensor now allows neuroscientists to map neural activity with molecular precision. This is the first time anyone has been able to map neural signals with high precision over large brain regions in living animals, offering a new window on brain function, says the lead researcher. The new work focused on the study of the neurotransmitter dopamine in a region called the ventral striatum, which...

Two types of neurons that enable the spinal cord to control skilled forelimb movement have been found by researchers. The first is a group of excitatory interneurons that are needed to make accurate and precise movements; the second is a group of inhibitory interneurons necessary for achieving smooth movement of the limbs. The findings are important steps toward understanding normal human motor function...

A subtype of Alzheimer's disease has been identified by neuroscientists that they say is neither well recognized nor treated appropriately. The variant, called hippocampal sparing AD, made up 11 percent of the 1,821 AD-confirmed brains examined by researchers -- suggesting this subtype is relatively widespread in the general population. It is estimated that 5.2 million Americans are living with AD....

Simply observing stressful situations can trigger a physical stress response, a new research paper suggests. ...

Researchers have discovered that stem cells taken from teeth can grow to resemble brain cells, suggesting they could one day be used in the brain as a therapy for stroke. ...

People with multiple sclerosis who for one year followed a plant-based diet very low in saturated fat had much less MS-related fatigue at the end of that year -- and significantly less fatigue than a control group of people with MS who didn't follow the diet, according to a study. "Fatigue can be a debilitating problem for many people living with relapsing-remitting MS," said one researcher. "So this...

Activity in areas of the brain related to reward and self-control may offer neural markers that predict whether people are likely to resist or give in to temptations, like food, in daily life, according to new research. ...

The first evidence that hyaluronic acid plays a role in epileptic seizures has been revealed, providing a potential new approach for treatments. While epilepsy is one of the most common neurological disorders—affecting approximately 1 percent of the population worldwide—it is one of the least understood. It is characterized by recurrent spontaneous seizures caused by the abnormal firing of neurons....

A wireless health-monitoring system that detects early signs of traumatic brain injury by continuously monitoring various brain and neural functions has been developed by engineers. "Wearable nanosensor systems can detect the severity of head injury by quantifying force of impact, be it light or violent," said an expert involved in the study. "In real time, our system continuously monitors neural activity...

An association between midlife and later life sleeping habits with memory has been discovered by researchers. This finding links extreme sleep durations to worse memory in later life. The study suggests that extreme changes in sleep duration from middle age to older age may also worsen memory function. This study was the first to evaluate associations of sleep duration at midlife and later life, and...

Stem cells derived from human body fat have been successfully used to deliver biological treatments directly to the brains of mice with the most common and aggressive form of brain tumor, significantly extending their lives, researchers say. The experiments advance the possibility that the technique could work in people after surgical removal of brain cancers to find and destroy any remaining cancer...

A new study could lead to better understanding of how brain processes are disrupted in patients with aphasia. ...

A new study reports on the brain's predictive nature when listening to others speak. ...

Researchers caution on the use of Brain Fingerprinting for criminal investigation. ...

Researchers discover stem cells taken from teeth can grow to resemble brain cells. They hope their discovery might pave the way for new treatments for stroke recovery. ...

Children looking at a loose thread on a jumper or an advert on the side of a bus might be 'blind' to oncoming traffic and other dangers when walking down the street. Researchers conclude that children under 14 are more likely than adults to be 'blinded' to their surroundings when focusing on simple things. It explains a somewhat frustrating experience familiar to many parents and carers: young children...

Neurosurgeons have, for the first time, combined real-time magnetic resonance imaging (MRI) technology with novel non-invasive cellular mapping techniques to develop a new biopsy approach that increases the accuracy of diagnosis for patients with brain cancer. As many as one third of brain tumor biopsies performed in the traditional manner can result in misdiagnosis. ...

In mice, a drug produces evidence of a mood lift within 24 hours and then continues working for sustained depression relief. A fast-acting antidepressant would be a welcome development for patients who must wait weeks for current drugs to take effect. ...
