Vision scientists demonstrate innovative learning method
New research published today in the journal Science suggests it may be possible to use brain technology to learn to play a piano, reduce mental stress or hit a curve ball with little or no conscious effort. It’s the kind of thing seen in Hollywood’s “M…
MIT– parts of brain can switch functions
Cambridge, MASS- When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex…

Monkey see: MRI technique finds big differences in human, primate sight
Researchers in Ohio say they’ve developed a way to use a decade-old imaging technology to directly compare the brains of monkeys and humans. Specifically, they used MRIs to compare parts of the monkey and human brains — the visual cortex — concerned with processing visual information. “Implicit in the neuroscience community was that the monkey cortex is a good model for the human cortex,” said one of the researchers. “Scientists didn’t have any choice but to make that assumption, as the monkey brain was the only model we had to work with.” But with the MRI they’ve found that there are in fact big differences.
