A different way to think about bodybuilding
Overeating and drug addiction may be linked, researchers findWASHINGTON - The same brain circuits are involved when obese people fill their stomachs as when drug addicts think about drugs, a finding that suggests overeating and addiction may be linked, U.S. researchers reported on Monday.
"We were able to simulate the process that takes place when the stomach is full, and for the first time we could see the pathway from the stomach to the brain that turns 'off' the brain's desire to continue eating."
"We thought the activated area (of the brain) must be in the satiety center, which we learned in medical school is supposed to be in the hypothalamus," Wang said in a telephone interview.
They used a positron emission tomography or PET scan to see which parts of the brain activated when the stimulator was activated. They also carefully questioned their volunteers, all of whom were very obese, about why and when they overate.
The stimulators also sent messages of satiety to brain circuits in the orbitofrontal cortex and striatum, which have been linked to craving and desire in cocaine addicts.
Addiction:From the Latin, it means ad-dict, to speak toward. There is a voice in the head that says, "do it again."
