By the time multiple sclerosis (MS) is diagnosed in children, it may be difficult to prevent the disabilities and relapses that come with the disease. In a new study, researchers examined MRI brain scans to identify children at high risk of developing MS before symptoms appear, which may lead to earlier diagnosis and treatment.

Researchers have found that inducing a biochemical alteration in brain proteins via the dietary supplement glucosamine was able to rapidly dampen that pathological hyperexcitability in rat and mouse models. These results represent a potentially novel therapeutic target for the treatment of seizure disorders, and they show the need to better understand the physiology underlying these neural and brain circuit changes.

New mechanism detected in Alzheimer’s disease

Researchers have discovered a cellular mechanism that may contribute to the breakdown of communication between neurons in Alzheimer’s disease. In the brain tissue of Alzheimer’s patients, the RNAs that encode synaptic proteins are degraded more rapidly than in healthy brain cells, the researchers found. Their findings indicate that inadequate levels of a protein known as RBFOX1 may be a factor in the faulty connections that are a hallmark of Alzheimer’s disease.

Human brain recalls visual features in reverse order than it detects them

New research has contributed to solving a paradox of perception, literally upending models of how the brain constructs interpretations of the outside world. When observing a scene, the brain first processes details — spots, lines and simple shapes — and uses that information to build internal representations of more complex objects, like cars and people. But during recall, the brain remembers those larger concepts first. This could shed light on concepts such as eyewitness testimony to autism.

Key component of respiratory center identified
Source: Science Daily
Star-shaped cells called astrocytes are much more than simple support cells in the brain. In a new study on mice, researchers demonstrate that they also play a key part in the respiratory center of the brainstem and release inflammatory molecules that regulate breathing. The results can provide important clues as to the causes of respiratory disease and the sudden unexpected postnatal collapse of newborn infants (SUPC).

How much can watching hockey stress your heart?
Source: Science Daily
A new study suggests that both the thrill of victory and the agony of defeat can have a substantial effect on the cardiovascular system. Investigators took the pulse of fans during a hockey game and found that on average, their heart rate increased by 75 percent when watching on TV, and by a whopping 110 percent (more than doubled, equivalent to the cardiac stress with vigorous exercise) when watching in person.

Mental training changes brain structure and reduces social stress
Source: Science Daily
Meditation can have positive effects on our health and well-being. However it has been unclear which mental practice has which effect, and what the underlying processes are. Researchers have discovered that different trainings affect either our attention or our social competencies and modify different brain networks. One mental technique was able to reduce the stress hormone cortisol. These results may influence the adaptation of mental trainings in clinics and education.
