Neuroimaging, gut peptides and obesity: novel studies of the neurobiology of appetite
2010
Journal of neuroendocrinology
Preserved Fulltext
For example, neuroimaging studies have shown that exposure to appetising food cues results in preferential activation of hedonic regions of the human brain, and that obese individuals show greater activation ...
Two studies have also combined hormones with neuroimaging of responses to food stimuli to examine the effect of long-term or genetic alterations of signalling on appetite and body weight in humans. ...

The present study examined whether personal food-related preferences would activate approach and avoidance systems, modulating spontaneous postural sway toward and away from food items. ...
Appetitive motivational states are fundamental neural and behavioral mechanisms underlying healthy and abnormal eating behavior, though their dynamic influence on food-related behavior is unknown. ...
The appetitive system is responsible for approach-related behavior, and is activated in response to pleasant and rewarding stimuli. ...
