Seeing life in fast-forward: Visual brain predicts future events based on past experience

For a long time, researchers thought of the visual cortex as a brain area that determines what you perceive based on information coming from the eyes. Neuroscientists now show that the area is also involved in the prediction of future events.

Mind-controlled device helps stroke patients retrain brains to move paralyzed hands

Stroke patients who learned to use their minds to open and close a plastic brace fitted over their paralyzed hands gained some ability to control their own hands when they were not wearing the brace, according to a new study. The participants, all of whom had moderate to severe paralysis, showed significant improvement in grasping objects.

Zika infections could be factor in more pregnancies

Zika virus infection passes efficiently from a pregnant monkey to its fetus, spreading inflammatory damage throughout the tissues that support the fetus and the fetus’s developing nervous system, and suggesting a wider threat in human pregnancies than generally appreciated.

Brain images reveal roots of kids’ increasing cognitive control

As children age into adolescence and on into young adulthood, they show dramatic improvements in their ability to control impulses, stay organized, and make decisions. Those ‘executive functions’ of the brain are key factors in determining outcomes, including educational success, drug use, and psychiatric illness. Now, researchers have mapped the changes in the network organization of the brain that underlie those improvements in executive function.

New brain mapping tool produces higher resolution data during brain surgery

Researchers have developed a new device to map the brain during surgery and distinguish between healthy and diseased tissues. The device provides higher resolution neural readings than existing tools used in the clinic and could enable doctors to perform safer, more precise brain surgeries.

Amazingly flexible: Learning to read in your 30s profoundly transforms the brain

Reading is such a modern cultural invention that there is no specific area in the brain dedicated to it. Scientists have found that learning to read as an adult reconfigures evolutionarily ancient brain structures hitherto assigned to different skills. These findings were obtained in a large-scale study in India in which completely illiterate women learned how to read and write for six months.
