Link found between resilience to dyslexia and gray matter in the frontal brain

24.07.2018 Health Problems

Dyslexia, a reading disorder, is characterized by a difficulty in “decoding”—navigating between the visual form and sounds of a written language. But a subset of dyslexic people, dubbed “resilient dyslexics,” exhibit remarkably high levels of reading comprehension despite difficulties decoding. What is the precise mechanism that allows certain individuals with dyslexia to overcome their low decoding abilities and ultimately extract […]

Are neurological disorders the result of brain evolution mistakes?

24.07.2018 Health Problems

A team of researchers affiliated with several institutions in Australia has proposed that some neurological disorders might have their roots in evolutionary mistakes. In their paper published in the journal Nature Neuroscience, the group describes their ideas and possible paths of research moving forward. As scientists delve ever deeper into our brains as part of an effort to understand how […]

Study provides insight into how dying neurons control eating behaviors of the brain microglia

24.07.2018 Health Problems

A new Mount Sinai study, published July 23 in the journal Nature Neuroscience, provides important insight into how microglia, cells that form a branch of the immune system inside the brain, go about their job of clearing out dying and non-functional neurons—and how they sometimes mistakenly attack healthy neurons, an event that can play a role in neurodegenerative diseases like […]

The brain distinguishes causes of errors to perform adaptation

17.07.2018 Health Problems

Practice is necessary to improve motor skills. Even if one performs poorly at first, one’s athletic performance improves through repeated exercise due to the reduction of motor errors as the brain learns. However, it’s important to remember that there are two types of errors: motor errors caused by poor motor control and target errors caused by unexpected target movements. For […]

As brain extracts meaning from vision, study tracks progression of processing

10.07.2018 Health Problems

Here’s the neuroscience of a neglected banana (and a lot of other things in daily life): whenever you look at its color—green in the store, then yellow, and eventually brown on your countertop—your mind categorizes it as unripe, ripe, and then spoiled. A new study that tracked how the brain turns simple sensory inputs, such as “green,” into meaningful categories, […]

Sleep disorder linked with changes to brain structure typical of dementia

06.07.2018 Health Problems

Obstructive sleep apnoea (OSA) is associated with changes to the structure of the brain that are also seen in the early stages of dementia, according to a study published in the European Respiratory Journal. OSA, where the walls of the throat relax and narrow during sleep stopping breathing, is known to reduce levels of oxygen in the blood. The new […]

What articulation-relevant brain regions do when we listen

05.07.2018 Health Problems

Brain regions that are involved in the articulation of language are also active in the perception of language. This finding of a team from the BrainLinks-BrainTools Cluster of Excellence of the University of Freiburg makes a significant contribution to clarifying a research question that has been hotly debated for decades. The scientists have published their results in the journal Scientific […]

Men and women have different genetic risk factors for developing brain cancer

28.06.2018 Health Problems

Glioma is the most common type of primary malignant brain tumor in the United States; glioblastoma being the most common type of glioma in adults. While sex differences in the incidence and survival rates of glioma were known, researchers had not investigated whether genetic differences based on sex could cast light on potential differences in the risk profile of glioma […]

A next-gen EEG could bring back lost brain function

28.06.2018 Health Problems

A device under development at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University could help bring back lost brain function by measuring how the brain responds to therapies that stimulate it with electric current. The approach could open new avenues for treating brain disorders and selectively switching brain activities on and off, says Anthony Norcia, a professor […]

Fit at midlife may mean healthier brain, stronger heart later

27.06.2018 Health Problems

(HealthDay)—If you’re fit in middle age, you might be guarding against not only depression as a senior, but also dying from heart disease if you do develop depression, a new study suggests. Among nearly 18,000 Medicare patients, the most fit were 16 percent less likely to develop depression, the researchers found. The most fit were also 56 percent less likely […]
