...reported in the Proceedings of the National Academy of Sciences in 2009, Corbetta's team found that spontaneous brain activity in two separate regions of the cerebral cortex appeared to be correlated after the participants had learned the visual task, but were not linked beforehand. The brain activity in those who were best at finding the hidden pattern onscreen was most strongly related. "Our test was like a video game. What this research shows is that we have a very dynamic landscape of ongoing activity [in the brain] even when we are at rest," notes Corbetta...
...question that has plagued researchers is whether the observed increase in brain activity that occurs after the completion of a mental task is just a ripple or echo effect, rather than a distinct event that helps solidify memories. Harvard researcher Dale Stevens believes he has more or less ruled out the former possibility by showing that even tasks that produce similar levels of neural activity while they are being performed, such as recognizing a face versus a landscape, result in different levels of activity after each task is completed. In Stevens' studies, brain activity remained high after people viewed landscapes...
...donations can save lives. Miraculous stories of rescue missions abound, operating rooms have been established, and urgent medical care is being delivered—but the resources are still outstripped by the need for them. As the rescue missions subside, the long-term task of rebuilding the infrastructure and public institutions in Haiti—a task that has often gone without proper international support for 200 years—will continue. As the international spotlight fades from Haiti, this task will become even more difficult...
Despite Harvard’s recent improvement, predicting the outcome of Friday’s match-up is no easy task. Princeton is just as streaky as its opponents...
...District Judge Vaughn Walker calls the lawyers back to hear closing arguments and issues his ruling. That is likely to take several weeks. But it's already clear that the verdict itself will be only a beginning, as all sides shift their focus from testimony to the real task of convincing federal appellate judges, and ultimately the U.S. Supreme Court, to rule their...
