Opioid antagonism modulates wanting-related frontostriatal connectivity

Theoretical accounts distinguish between motivational (‘wanting’) and hedonic (‘liking’) dimensions of rewards. Previous animal and human research linked wanting and liking to anatomically and neurochemically distinct brain mechanisms, but it remains unknown how the different brain regions and neuro...

description	Theoretical accounts distinguish between motivational (‘wanting’) and hedonic (‘liking’) dimensions of rewards.

Here, we assessed how pharmacological manipulations of opioid and dopamine receptor activation modulate the neural processing of wanting and liking in humans in a randomized, placebo-controlled, double-blind clinical trial.
