  1. Exercise for stroke patients' brains

    Researchers found that while the typical brain responded to the visual stimulus with activity in cortical motor regions that are generally activated when we watch others perform actions, in the stroke-affected brain, activity was strongest in these regions of the damaged hemisphere, and strongest when stroke patients viewed actions they would have the most difficulty performing.

  2. Smarter Children Have More Gray Matter 60 Years Later

    Your IQ at the age of eleven predicts your brain anatomy sixty years later, according to a Canadian/Scottish team of neuroscientists: Childhood cognitive ability accounts for associations between cognitive ability and brain cortical thickness in old age. The authors of the new paper, Karama et al, made use of a unique long-term study of Scottish volunteers, all of whom had IQ tests back in 1947 ...

  3. Brain Aging May Depend on Childhood Intelligence

    Older people who stay sharp tend to have a thicker cortex, which is the outermost region of the brain that includes the areas responsible for judgment and complex thought. But while preserving the cortex is important for successful aging, a new study suggests that childhood intelligence — not anything specific done in old age — largely accounts for why some elderly people have more cortical ...

  3. "One intriguing possible explanation for this discrepancy is that the cortical neurons might be acting as `coincidence detectors,'" said Buck. "They might respond only when they get input from more than one type of odorant receptor. And this...
