This study aims to investigate, through behavioural tests combined with advanced neurofunctional methods, the neural bases of intentional behaviours towards edible stimuli using explicit and implicit paradigms in normal-weight subjects.

This knowledge will then be expanded with the study of associations between behavioral/neurofunctional measures and blood/hummon parameters.

Inclusion Criteria:

• Normal weight (Body mass index - BMI - comprised between 18.6 and 24.99.
• Absence of usual contraindications to MRI examination (e.g. pacemakers, fixed hearing implants, presence of metallic foreign bodies, intrauterine bodies, metallic splinters or fragments, metallic prostheses, screws, nails, fixed or mobile dental prostheses).
• Signature of informed consent and consent to cooperate in all study procedures.

Exclusion Criteria:

• Previous diagnosis of significant neurological disorders (brain damage or dementia), major psychiatric disorders or eating disorders (binge-eating disorder, bulimia).
• BMI less than 18.5 and greater than or equal to 25 Kg/cm2.
