Kent Berridge, Professor of Psychology and Neuroscience at the University of Michigan, Ann Arbor, discusses his lab’s research into fundamental question about the brain and behavior. He discusses how food pleasure is generated in the brain, the neural bases of wanting and liking, and how fear and stress relate to desire.

From CNN:

The radiation emitted after just 50 minutes on a mobile phone increases the activity in brain cells, according to a new government-funded study.

The effects of that brain activity are not known, said the researchers, who called for more study.

Phones that were turned off did not create the same brain activity.

The small study, published in the Journal of American Medical Association, is the first to look specifically at how electromagnetic radiation from cell phones affects glucose metabolism, a normal function, in the brain.

“When glucose metabolism goes up, it activates cells. The findings are an indication that exposure to cell phones activate the brain much more easily than we previously thought,” said Dr. Nora Volkow, National Institutes of Health neuroscientist and lead study author.

Brain activity means that the cells are using glucose to create energy. The brain normally produces the amount of glucose it needs to function properly. But these new findings don’t tell us whether activating the cells artificially, in this case by cell phone radiation, will have a negative effect on health. Volkow says she simply doesn’t know and calls for further investigation.
