It is becoming clearer how neurobiological mechanisms generate 'liking'and
'wanting'components of food reward. Mesocorticolimbic mechanisms that enhance …

Background: Behaviour change interventions are effective in supporting individuals in
achieving temporary behaviour change. Behaviour change maintenance, however, is rarely …

A decade ago, we hypothesized that drug addiction can be viewed as a transition from
voluntary, recreational drug use to compulsive drug-seeking habits, neurally underpinned by …

The nucleus accumbens is a major input structure of the basal ganglia and integrates
information from cortical and limbic structures to mediate goal-directed behaviors. Chronic …

The basolateral amygdala (BLA) mediates associative learning for both fear and reward.
Accumulating evidence supports the notion that different BLA projections distinctly alter …

Midbrain dopamine neurons are well known for their strong responses to rewards and their
critical role in positive motivation. It has become increasingly clear, however, that dopamine …

We review the current state of knowledge on the computational and neural mechanisms of
reinforcement-learning with a particular focus on fronto-striatal circuits. We divide the …

Reward-related cues are an important part of our daily life as they often influence and guide
our actions. This paper reviews one of the experimental paradigms used to study the effects …

Recent behavioral studies in both humans and rodents have found evidence that
performance in decision-making tasks depends on two different learning processes; one …

Evidence supports at least two methods for learning about reward and punishment and
making predictions for guiding actions. One method, called model-free, progressively …
