Concept learning, the ability to extract commonalities and highlight distinctions across a set
of related experiences to build organized knowledge, is a critical aspect of cognition …

The prefrontal cortex (PFC) is a heterogeneous area that is critical to reward-based decision-
making. In particular, the dorsal anterior cingulate cortex, ventromedial PFC and orbitofrontal …

The recent years have witnessed a dramatic increase in the use of reinforcement learning
(RL) models in social, cognitive and affective neuroscience. This approach, in combination …

Humans learn from their own trial-and-error experience and observing others. However, it
remains unknown how brain circuits compute expected values when direct learning and …

Humans often face the challenge of making decisions between ambiguous options. The
level of ambiguity in decision-making has been linked to activity in the parietal cortex, but its …

When choosing between options, whether menu items or career paths, we can evaluate how
rewarding each one will be, or how congruent it is with our current choice goal (eg, to point …

Decisions are based on value expectations derived from experience. We show that dorsal
anterior cingulate cortex and three other brain regions hold multiple representations of …

To decide optimally between available options, organisms need to learn the values
associated with these options. Reinforcement learning models offer a powerful explanation …

Uncertainty permeates decisions from the trivial to the profound. Integrating brain and
behavioral evidence, we discuss how probabilistic (varied outcomes) and temporal (delayed …

We are remarkably adept at inferring the consequences of our actions, yet the neuronal
mechanisms that allow us to plan a sequence of novel choices remain unclear. We used …
