Overview
Brief Summary
In this project, the investigators will explore the cognitive neuroscience of intentional action in relation to food behaviour. To unravel how the brain systems involved in intentional control of actions and how these interact with the reward system in different physiological conditions and in relation to lean-weight or obesity, the investigators will manipulate the degree of intentionality of the behaviours under examination and the level of satiety of the participants.

Outcomes
Primary Outcomes
BOLD (Blood Oxygen Level Dependent) signal
Time Frame: This outcome will be measured on the recruitment day
The investigators will measure the changes of the hemodynamic response (BOLD signal) recorded in the whole brain during the execution of the different experimental tasks (e.g. intentionally guided actions towards stimuli of high or low calories food vs externally guided actions towards stimuli of high or low calories food), in the two groups (fasted and satiated subjects).
