Data from previous neuroimaging studies exploring neural activity associated with
uncertainty suggest varying levels of activation associated with changing degrees of …

Behavioral studies have shown for decades that humans are sensitive to risk when making
decisions. More recently, brain activities have been shown to be correlated with risky …

Environments furnish multiple information sources for making predictions about future

Gambling disorder (GD) is a behavioral addiction that may be linked to alterations in
dopamine (DA) systems. Gambling involves chronic exposure to uncertain reward, which …

Purpose The aim of this study was to describe imaging markers of decision-making under
uncertain conditions in normal individuals, in order to provide baseline activity to compare to …

Most real-world decisions involve a delicate balance between exploring unfamiliar
alternatives and committing to the best known option. Previous work has shown that humans …

Previous functional MRI studies reported neural correlates of risk and ambiguity based on
behavioral economic theories. A recent study controlled for uncertainty by adding noise to …

In our everyday life we often have to make decisions with uncertain consequences, for
instance in the context of investment decisions. To successfully cope with these situations …

How do individuals decide to act based on a rewarding status quo versus an unexplored
choice that might yield a better outcome? Recent evidence suggests that individuals may …
