Acute and chronic changes in myelin following mild traumatic brain injury

tir, 05/01/2018 - 13:55
Preliminary research using mcDESPOT magnetic resonance imaging shows changes in the myelin content of white matter in the brain following mild traumatic brain injury. Myelin changes are apparent at the time of injury and three months afterward.

EEG signals accurately predict autism as early as 3 months of age

tir, 05/01/2018 - 13:51
Autism is challenging to diagnose, especially early in life. A new study shows that inexpensive EEGs, which measure brain electrical activity, accurately predict or rule out autism spectrum disorder in infants, even in some as young as three months.

Physicists find properties of magnetic soliton of interest for brain-inspired computing

tir, 05/01/2018 - 13:38
A team of physicists has uncovered properties of a category of magnetic waves relevant to the development of neuromorphic computing -- an artificial intelligence system that seeks to mimic human-brain function.

Brain's window for language learning open until adulthood

tir, 05/01/2018 - 13:38
It has long been known that children learn language more easily than adults, but determining exactly when that ability declines has been something of a mystery. Researchers now report that prime language learning years extend approximately a decade longer than previously thought -- until 17.4 years of age. The new findings hold implications for neuroscience, linguistics, developmental psychology and public policy.

Diagnostic imaging computers outperform human counterparts

man, 04/30/2018 - 21:05
The 'deep learning' computers in a diagnostic imaging lab routinely defeat their human counterparts in diagnosing heart failure, detecting various cancers and predicting their strength. But nonetheless researchers dismiss any notion that such machines might someday replace pathologists and radiologists.

Youth tackle football participation linked to earlier onset of cognitive and emotional symptoms

man, 04/30/2018 - 18:19
Starting to play tackle football before age 12 could lead to earlier onset of cognitive and emotional symptoms among athletes who were diagnosed with CTE and other brain diseases postmortem, according to a new study.

Editing brain activity with holography

man, 04/30/2018 - 18:19
The goal of brain implants is to read neuron activity and respond by activating neurons to, for example, move prosthetics or simulate lost perceptions. Researchers have developed a device to do that, projecting a holographic image into the top layer of the brain to activate dozens of neurons hundreds of times a second to simulate real patterns of activity. Equipped with new, fast on/off optogenetic switches, neurons are tricked into perceiving things not there.

Calcium-based MRI sensor enables more sensitive brain imaging

man, 04/30/2018 - 18:19
Neuroscientists have developed an MRI sensor that lets them monitor neuron activity deep within the brain by tracking calcium ions. This type of sensing could allow researchers to link specific brain functions to their pattern of neuron activity, and to determine how distant brain regions communicate with each other during particular tasks.

Personal care products contribute to a pollution 'rush hour'

man, 04/30/2018 - 18:18
When people are out and about, they leave plumes of chemicals behind them -- from both car tailpipes and the products they put on their skin and hair. In fact, emissions of siloxane, a common ingredient in shampoos, lotions, and deodorants, are comparable in magnitude to the emissions of major components of vehicle exhaust, such as benzene, from rush-hour traffic.

New models could uncover important answers for Alzheimer's researchers

man, 04/30/2018 - 18:17
Alzheimer's disease currently affects more than 5.5 million Americans and is one of the costliest diseases to treat, according to the Alzheimer's Association. Characterized by a buildup of plaque in the brain, few animal models exist that researchers could use to study this devastating disorder. Now a team of researchers has developed a rat model that can be used to study the buildup of amyloid plaques and vascular abnormalities in the brain.

Potential for more precise diagnosis and treatment of TBI

man, 04/30/2018 - 15:25
Patients who've suffered from traumatic brain injuries have changes in tiny blood vessels in their brains that researchers believe are linked to a range of cognitive symptoms. The findings may help doctors pinpoint specific types of TBIs and tailor personalized therapies.

Chronic dizziness can result from, or trigger, psychiatric disorders

man, 04/30/2018 - 15:25
Dizziness can fall into a number of broad categories, including vertigo (spinning sensation), presyncope (near-fainting), and disequilibrium (imbalance). When a patient's description of symptoms appears consistent with one of these categories, physicians are better equipped to make an accurate diagnosis. Patients who have a difficult time describing their symptoms, or seem to experience several different symptoms, are likely experiencing non-specific dizziness -- which should be a cue for physicians to ask about the patient's mental health.
