Girls mature faster than boys.
New knowledge inspect suggests one why girls mature faster than boys during their teen years. As men and women age, their brains reorganize and modify connections. In this study, scientists examined wit scans from 121 sturdy people, aged 4 to 40. It's during this space that the major changes in intelligence connectivity occur provillus. The researchers discovered that although the overall multitude of connections is reduced, the wisdom preserves long-distance connections important for integrating information.
The findings might make plain why brain banquet doesn't decline - but instead improves - during this years of connection pruning, according to the scrutiny team. The researchers also found that these changes in understanding connections begin at an earlier age in girls than in boys vito mol. "Long-distance connections are nit-picking to establish and make a stand for but are crucial for fast and efficient processing," said contemplation co-leader Marcus Kaiser, of Newcastle University, in England.

People With Stroke Have A Chance At A Full Life
People With Stroke Have A Chance At A Full Life.
Scientists are testing a untrodden thought-controlled hallmark that may one age cure people bestir oneself limbs again after they've been paralyzed by a stroke. The tool combines a high-tech brain-computer interface with electrical stimulation of the damaged muscles to ease patients relearn how to deed frozen limbs whos phil. So far, eight patients who had spent flicker in one hand have been through six weeks of group therapy with the device.
They reported improvements in their ability to unbroken daily tasks. "Things like combing their curls and buttoning their shirt," explained learning author Dr Vivek Prabhakaran, leader of functional neuroimaging in radiology at the University of Wisconsin-Madison. "These are patients who are months and years out from their strokes muscleadvance. Early studies suggested that there was no true leeway for replacement for these patients, that they had plateaued in the recovery.
We're showing there is still allowance for change. There is plasticity we can harness". To use the young tool, patients have a cap of electrodes that picks up brain signals. Those signals are decoded by a computer increase lean body m decrease fat. The computer, in turn, sends diminutive jolts of tension through wires to muggy pads placed on the muscles of a patient's paralyzed arm.
The jolts role of for instance nerve impulses, considerable the muscles to move. A simple video ploy on the computer screen prompts patients to turn to hit a target by moving a ball with their seized arm. Patients practice with the game for about two hours at a time, every other day.
