Neural structural abnormalities behind altered brain activation in obesity: Evidence from meta-analyses of brain activation and morphometric data.

Obesity represents a risk factor for disability with a major bearing on life expectancy. Neuroimaging techniques are contributing to clarify its neurobiological underpinnings. Here, we explored whether structural brain abnormalities might accompany altered brain activations in obesity.

Neurofunctional correlates of body-ownership and sense of agency: A meta-analytical account of self-consciousness.

Self-consciousness consists of several dissociable experiences, including the sense of ownership of one's body and the sense of agency over one's action consequences. The relationship between body-ownership and the sense of agency has been described by different neurocognitive models, each providing specific neurofunctional predictions. According to an "additive" model, the sense of agency entails body-ownership, while an alternative "independence" hypothesis suggests that they represent two qualitatively different processes, underpinned by distinct brain systems.
