Mental illness: Special form of RNA in brain

Circular RNA may play a role in schizophrenia and bipolar disorder.

Stimulation of nerve cluster during stroke may have beneficial effects

Promising new stimulation treatment increases blood flow to the brain, improves hand strength in patients with minor stroke and may decrease disability in many patients with stroke. Nerve cluster stimulation could provide a new treatment option to stro…

Casting light on the brain’s inner workings

A team of engineers has created an ultra-small, wireless, battery-free device that uses light to record individual neurons so neuroscientists can see how the brain is working.

Long-distance skiers may have ‘motor reserve’ that can delay onset of Parkinson’s disease

To better understand the relationship between physical activity and Parkinson’s Disease (PD) investigators in Sweden analyzed medical records of nearly 200,000 long-distance skiers who took part in the Vasaloppet cross-country ski race. They establishe…

Initial protective role of nervous system’s ‘star-shaped cells’ in sporadic motor neuron disease uncovered

Support cells in the nervous system help protect motor neurons in the early-stages of sporadic motor neuron disease, according to new research from the Crick and UCL.

Alcoholism in the family affects how your brain switches between active and resting states

A new study shows that just having a parent with an alcohol use disorder affects how your brain transitions between active and resting states — regardless of your own drinking habits.

The human brain’s meticulous interface with the bloodstream now on a precision chip

It can be the bain of brain drug developers: The interface between the human brain and the bloodstream, the blood-brain-barrier, is so meticulous that animal models often fail to represent it. This improved chip represents important features more accur…

Long-term learning requires new nerve insulation

Scientists have discovered that mice quickly learn a fearful response to a situation perceived as threatening, but for such a conditioned response to become long-lasting requires brain cells to increase amounts of an insulating material called myelin.

AI, brain scans may alter how doctors treat depression

Artificial intelligence may soon play a critical role in choosing which depression therapy is best for patients.

Sensory perception is not superficial brain work

How does the brain decide which of the senses it will focus attention on when two interact? For the first time, scientists measured the sensory signals at different depths in the cortex.
