...purpose of the scans was to compare the relative levels of spontaneous neural activity in two key brain regions involved in memory - the hippocampus and visual cortex - during rest, both before and after the visual tasks. The NYU team noticed that levels of activity in the two areas were more closely correlated several minutes after people had looked at the images than before they started the experiment. That suggests that the visual-learning tasks had affected the brain's seemingly random firings during rest, and perhaps that the brain was conducting memory-consolidating activity during that time...

What's more, the more closely correlated the brain activity during the rest period, the better the person performed on the tests of recognition. "We found that higher correlations [of activity in the hippocampus and visual cortex] during rest periods leads to high future memory," notes Arielle Tambini, a graduate student in Davachi's lab and lead author of the paper...

While the NYU study tested memory and simple recognition, other recent research looking at activity in the brain at rest and the learning of complex visual tasks has yielded similar results. Neurologist Maurizio Corbetta of Washington University in St. Louis recruited 14 people to use their peripheral vision to identify a hidden pattern - an inverted T - that was flashed briefly on a screen inside an fMRI machine. After each daily training session, lasting one to two hours for about a week, participants were given an hour's rest, during which time Corbetta scanned their brains. (Read "The fMRI Brain Scan...

...exhibits being offered into evidence, among them multiple diagrams of the scene of the shooting and incriminating documents allegedly written by Siddiqui. At one point a key government eyewitness stepped off the witness stand and out of range of both the camera and microphone to use a visual aid to demonstrate where he was during the shooting. He was permitted to give much of his testimony off camera...

Konda said that the development of a Harvard version of Craigslist has been attempted several times before, but preceding versions ultimately fizzled out because they were either difficult to navigate or lacking in visual appeal...
