Rhythmic Fluctuations in Evidence Accumulation during Decision Making in the Human Brain
Categorical choices are preceded by the accumulation of sensory evidence in favor of one action or another. Current models describe evidence accumulation as a continuous process occurring at aExpand

Self-Other Mergence in the Frontal Cortex during Cooperation and Competition
Summary To survive, humans must estimate their own ability and the abilities of others. We found that, although people estimated their abilities on the basis of their own performance in a rationalExpand

Beyond negative valence: 2-week administration of a serotonergic antidepressant enhances both reward and effort learning signals
To make good decisions, humans need to learn about and integrate different sources of appetitive and aversive information. While serotonin has been linked to value-based decision-making, its role inExpand

The Good, the Bad, and the Irrelevant: Neural Mechanisms of Learning Real and Hypothetical Rewards and Effort
Natural environments are complex, and a single choice can lead to multiple outcomes. Agents should learn which outcomes are due to their choices and therefore relevant for future decisions and whichExpand

Simultaneous representation of a spectrum of dynamically changing value estimates during decision making
TLDR
We show that dorsal anterior cingulate cortex and three other brain regions hold multiple representations of choice value based on different timescales of experience organized in terms of systematic gradients across the cortex. Expand

Excitation and inhibition in anterior cingulate predict use of past experiences
Dorsal anterior cingulate cortex (dACC) mediates updating and maintenance of cognitive models of the world used to drive adaptive reward-guided behavior. We investigated the neurochemicalExpand

A Role Beyond Learning for NMDA Receptors in Reward-Based Decision-Making—a Pharmacological Study Using d-Cycloserine
N-methyl-D-aspartate (NMDA) receptors are known to fulfill crucial functions in many forms of learning and plasticity. More recently, biophysical models, however, have suggested an additional role ofExpand

Prospection, Perseverance, and Insight in Sequential Behavior
Summary Real-world decisions have benefits occurring only later and dependent on additional decisions taken in the interim. We investigated this in a novel decision-making task in humans (n = 76)Expand
