Behavioural neuroscience: It's good to give
Why does it feel good to give even at a cost to oneself, and even anonymously? In a new study, Jorge Moll and colleagues have used functional neuroimaging to investigate the neural source of the 'joy of giving'. They find that charitable donations activate the same neural systems as those that respond to monetary reward.
