Why can some people easily stop eating when they are full and others can't, which can lead to obesity? A new study has found one reason may be a newly discovered structural connection between two regions in the brain that appears to be involved in regulating feeding behavior. These regions involve the sense of smell and behavior motivation.
Why can some people easily stop eating when they are full and others can't, which can lead to obesity? A new study has found one reason may be a newly discovered structural connection between two regions in the brain that appears to be involved in regulating feeding behavior. These regions involve the sense of smell and behavior motivation.The weaker the connection between these two brain regions, the higher a person's Body Mass Index, the scientists report.
The weaker the connection between these two brain regions, the higher a person's Body Mass Index , the Northwestern scientists report. Scientists have not fully understood the neural underpinnings of how the sense of smell contributes to how much we eat. But people with weak or disrupted circuits connecting these areas may not get these stop signals, and may keep eating even when they aren't hungry, the scientists said.
"Future studies will be needed to uncover the exact mechanisms in the brain that regulate eating behavior," Zelano said.
