Brain imaging can tell how intelligent you are:

Brain imaging can predict how intelligence varies from exceptionally smart humans to the average ones, a new research has said. “Our research shows that connectivity a particular part of the prefrontal cortex can predict how intelligent someone is,” lead author Michael W Cole, a postdoctoral research fellow in cognitive neuroscience aw Washington University said.

 The study suggests that another 10% of individual differences in intelligence can be explained by the strength of neural pathways connecting the left lateral prefrontal cortex to the rest of the brain.

It has been pointed out that the brain’s lateral prefrontal cortex, a region just behind the temple, is a critical hub for high-level mental processing, with activity levels there predicting another 5% of variation in individual intelligence.

The findings establish “global brain connectivity” as a new approach for understanding human intelligence.

The study is the first to provide compelling evidence that neural connections between the lateral prefrontal cortex and the rest of the brain make a unique and powerful contribution to the cognitive processing underlying human intelligence, says Cole.

“This study suggests that part of what it means to be intelligent is having a lateral prefrontal cortex that does its job well; and part of what that means is that it can effectively communicate with the rest of the brain,” study co-author Todd Bravers said. (Times of India)

Coffee can help reduce Parkinson’s symptoms

Tow cups of coffee a day can help relieve the movement-related symptoms associated with Parkinson’s disease, a new research has claimed. Researchers from McGill University in Montreal found patients give caffeine supplements averaged a five-point improvement in symptoms compared to those given a placebo, the Daily Mail reported.

“This is a modest improvement but may be enough to provide benefit to patients,” Professor Ronald Postuma from the university, said. “It may not be sufficient to explain the relationship between caffeine non-use and Parkinson’s since studies of progressions of Parkinson’s symptoms early in the disease suggesting a five-point reduction would delay diagnosis by only six months,” Postuma was quoted by the paper as saying.
