Value, search, persistence and model updating in anterior cingulate cortex
Dorsal anterior cingulate cortex (dACC) carries a wealth of value-related information necessary
for regulating behavioral flexibility and persistence. It signals error and reward events …

[PDF][PDF] Self-other mergence in the frontal cortex during cooperation and competition
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 rational …

[HTML][HTML] Predictive decision making driven by multiple time-linked reward representations in the anterior cingulate cortex
In many natural environments the value of a choice gradually gets better or worse as
circumstances change. Discerning such trends makes predicting future choice values possible. We …

The good, the bad, and the irrelevant: neural mechanisms of learning real and hypothetical rewards and effort
…, N Kolling, N Nelissen, MK Wittmann… - Journal of …, 2015 - Soc Neuroscience
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 …

[HTML][HTML] Global reward state affects learning and activity in raphe nucleus and anterior insula in monkeys
People and other animals learn the values of choices by observing the contingencies between
them and their outcomes. However, decisions are not guided by choice-linked reward …

[HTML][HTML] Simultaneous representation of a spectrum of dynamically changing value estimates during decision making
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 choice …

[HTML][HTML] Neural mechanisms for learning self and other ownership
Sense of ownership is a ubiquitous and fundamental aspect of human cognition. Here we
