The so-called reward center of the brain may need a new name, say scientists who have shown it responds to good and bad experiences.

Brain's 'reward' center also responds to bad experiences

The finding, published in PLoS One, may help explain the "thrill" of thrill-seeking behavior or maybe just the thrill of surviving it, according to scientists at Georgia Health Sciences University and East China Normal University. Eating chocolate or falling off a building -- or just the thought of either -- can evoke production of dopamine, a neurotransmitter that can make the heart race and motivate behavior, said Dr. Cellphone Use Tied to Brain Changes.

Researchers from the National Institutes of Health have found that less than an hour of cellphone use can speed up brain activity in the area closest to the phone antenna, raising new questions about the health effects of low levels of radiation emitted from cellphones.

Cellphone Use Tied to Brain Changes

The researchers, led by Dr. Nora D. Volkow, director of the National Institute on Drug Abuse, urged caution in interpreting the findings because it is not known whether the changes, which were seen in brain scans, have any meaningful effect on a person’s overall health. But the study, published Wednesday in The Journal of the American Medical Association, is among the first and largest to document that the weak radio-frequency signals from cellphones have the potential to alter brain activity.

“The study is important because it documents that the human brain is sensitive to the electromagnetic radiation that is emitted by cellphones,” Dr. Edward Osborne Wilson. Edward Osborn Wilson. Edward Osborn Wilson ( b. 1929, Birmingham AL) Former Frank B.

The Twitter Spot in Your Brain

And, if you check their online profiles, they actually do have thousands of friends and followers. But are these real friends, or did the supposed expert socializers simply crank up an automation software to rapidly build their follower base? Surprisingly, how capable of being social a person is can be revealed by a brain scan. A new study has found that individuals with larger amygdalas (an area of the brain usually associated with fear and other emotions) have more friends and more complex social networks. What Happened to the Hominids Who May Have Been Smarter Than Us? Even if brain size accounts for just 10 to 20 percent of an IQ test score, it is possible to conjecture what kind of average scores would be made by a group of people with 30 percent larger brains.

What Happened to the Hominids Who May Have Been Smarter Than Us?

We can readily calculate that a population with a mean brain size of 1,750 cc would be expected to have an average IQ of 149. This is a score that would be labeled at the genius level. And if there was normal variability among Boskops, as among the rest of us, then perhaps 15 to 20 percent of them would be expected to score over 180. Return of the "amazing" Boskops.
