Obesity is a neurobehavioral disorder that results from a combination of overeating and
insufficient physical activity. Finely tuned mechanisms exist to match food intake to caloric …

Obesity is predominantly caused by overeating, an abnormal behaviour for which there is no
unequivocal neurophysiological explanation. Functional neuroimaging techniques, such as …

Appetite and body weight regulation are controlled by the central nervous system (CNS) in a
rather complicated manner. The human brain plays a central role in integrating internal and …

The dysregulation of food intake in chronic obesity has been explained by different theories.
To assess their explanatory power, we meta-analyzed 22 brain-activation imaging studies …

The mere sight of foods may activate the brain's reward circuitry, and humans often
experience difficulties in inhibiting urges to eat upon encountering visual food signals …

Neuroimaging is becoming increasingly common in obesity research as investigators try to
understand the neurological underpinnings of appetite and body weight in humans. Positron …

Adequate energy intake is vital for the survival of humans and is regulated by complex
homeostatic and hedonic mechanisms. Supported by functional MRI (fMRI) studies that …

Functional, molecular and genetic neuroimaging has highlighted the existence of brain
anomalies and neural vulnerability factors related to obesity and eating disorders such as …

The neural systems regulating food intake in obese individuals remain poorly understood.
Previous studies applied positron emission tomography and manipulated hunger and satiety …

The control of food intake and energy metabolism depends on the interaction among energy
homeostasis, emotional factors (including the hedonic aspects of food), and environmental …
