A new mathematical method can detect geometric structure in neural activity in the brain. Says Vladimir Itskov, associate professor of mathematics at Penn State: “Previously, in order to understand this structure, scientists needed to relate neural activity to some specific external stimulus. Our method is the first to be able to reveal this structure without… Read more

For many years scientists have been trying to find a way to measure the pressure in a patient’s brain without having to drill a hole in the person’s skull. Although this remains the most reliable way to measure pressure in the brain, it is invasive, expensive and comes with the risk of infection and bleeding… Read more

A new study from the University of Geneva suggests that receiving rewards as you learn can help cement new facts and skills in your memory, particularly when combined with a daytime nap. The findings reveal that memories associated with a reward are preferentially reinforced by sleep. Even a short nap after a period of learning… Read more

For the first time, researchers have used a cocktail of small molecules to transform human brain cells, called astroglial cells, into functioning neurons for brain repair. The new technology opens the door to the future development of drugs that patients could take as pills to regenerate neurons and to restore brain functions lost after traumatic… Read more

Helper cells in the brain, which support nerve function, change their behaviour with the progression of motor neuron disease (MND), a new study has found. Researchers at the Sheffield Institute for Translational Neuroscience (SITraN) discovered the star-shaped cells, called astrocytes, progressively lose the ability to support motor neurons as MND progresses leading to the death… Read more
