Can a brain scan reveal how smart you are?

A question has plagued scientists for years: When it comes to intelligence, what distinguishes the brains of exceptionally smart humans from the rest? New research reveals that a brain scan could offer an answer.

The brain’s mass and the size of its prefrontal cortex – a region just behind the forehead – have long been believed to play a role in intelligence. New research published in the St. Louis-based Washington University Journal of Neuroscience suggests that up to ten percent of individual differences in intelligence lie in the strength of neural pathways between the brain and the left prefrontal cortex – the region linked to personality and cognitive behaviors.

In other words, the better and more efficient the neural pathways are, the more intelligent the person is. It is a new approach for understanding human intelligence, dubbed “global brain connectivity.”

This marks the first example of solid evidence that neural connections between the left prefrontal cortex and the rest of the brain are a powerful contributing factor to human intelligence, said the study’s lead author Michael W. Cole, PhD, a postdoctoral research fellow in cognitive neuroscience at Washington University. Read the rest of this entry »

Syria Massacre Captured By Satellite Cameras (PHOTOS)

Syria Massacre

WASHINGTON — New satellite images of the besieged Syrian region of Houla provide stark evidence of last week’s massacre of more than 100 civilians, many of themchildren, believed killed by government forces loyal to President Bashar Assad’s regime.

The before and after photos were taken last Friday and Saturday by DigitalGlobe, a commercial satellite company that provided them exclusively to The Huffington Post. They appear to confirm on-the-ground reports of mass casualties from execution-style killings and shelling of civilians by government troops.

The photos, in the slideshow below, show the village of Taldou, two miles southeast of central Houla.

In one set of images, the city center is seen on the morning of May 25, before the violence began. No unusual activity is obvious.

A second image taken the next day, Saturday, shows what the company said are large crowds massed around the local mosque near the town square. “That was the first tip-off,” said Amy Opperman, a manager in the DigitalGlobe Analysis Center, noting that such crowds are more typical of Friday, the Muslim day of prayer.

The people stand near a line of long, light-colored trenches that are believed to be themass burials photographed by a Reuters photographer on the scene. Analysts compared a clock tower, power lines and other features seen in the photo to confirm the satellite image was a match. Read the rest of this entry »

Four-Year-Old Girl With Sky-High IQ Joins Mensa

Meet a 4-year-old girl whose IQ is just one point shy of Stephen Hawking and Albert Einstein. Legos first, the theory of relativity next.

Heidi Hankins, from Winchester, England, is the newest kid on the block to join Mensa, the intellectual organization, with an IQ of 159. At the age of 2, Hankins was reportedly already reading at an 8-year-old level. There are no standardized IQ tests for children under the age of 10, so the toddler was psychologically evaluated.

Back in 2009, Oscar Wrigly joined Mensa at the age of 2 with an IQ of 160 to become the youngest child to ever join the organization. The average IQ in the general population is said to be about 100. Read the rest of this entry »

Intelligent Humans Evolved To Worry, Say Scientists

Posted by Ram Kumar Shrestha on April 13, 2012


Comment: Never try to be happy with respect to something else. There is no guarantee that you will be able to control others. So try to make yourself frame of reference if you really want to be happy:

A new study by researchers at SUNY Downstate Medical Center in the US suggests that excess worrying could be a sign of intelligence.

Scientists found that high intelligence and worry both correlate with brain activity measured by the depletion of the nutrient choline in the subcortical white matter of the brain. According to the researchers, this suggests that intelligence may have co-evolved with worry in humans.

“While excessive worry is generally seen as a negative trait and high intelligence as a positive one, worry may cause our species to avoid dangerous situations, regardless of how remote a possibility they may be,” said Jeremy Coplan, MD, professor of psychiatry at SUNY Downstate.
