Neural Bases of Decision-making in Healthy Individuals

The goal of this single center non-interventional fMRI study is to assess the neural bases of decision-making and executive functioning in healthy individuals,and whether/how their responsiveness is modulated by ageing. The main questions it aims to answer are: 1. are there specific neural correlates for ageing effects on executive functioning (particularly inhibitory control) and decision-making? 2. Is there a relationship, at the behavioral and neural levels, between ageing-related changes in executive functioning and decision-making? Healthy participants will be recruited for 1. a behavioral assessment including multiple tests of decision-making and executive functioning/inhibitory control; 2. a fMRI session to collect data concerning a) brain activity associated with decision-making and executive functioning, b) brain structural morphometriy (grey-matter volume/density), and c) brain structural connectivity (diffusion weighted imaging). Results will provide an useful baseline for investigating alterations of decision-making and executive functioning, and of their neural bases, in pathological conditions.
