Value, search, persistence and model updating in anterior cingulate cortex

N Kolling, MK Wittmann, TEJ Behrens… - Nature …, 2016 - nature.com
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

MK Wittmann, N Kolling, NS Faber, J Scholl… - Neuron, 2016 - cell.com
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

MK Wittmann, N Kolling, R Akaishi, BKH Chau… - Nature …, 2016 - nature.com
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 …

Ventral anterior cingulate cortex and social decision-making

PL Lockwood, MK Wittmann - Neuroscience & Biobehavioral Reviews, 2018 - Elsevier
Studies in the field of social neuroscience have recently made use of computational models
of decision-making to provide new insights into how we learn about the self and others …

Neural mechanisms of social cognition in primates

MK Wittmann, PL Lockwood… - Annual review of …, 2018 - annualreviews.org
Activity in a network of areas spanning the superior temporal sulcus, dorsomedial frontal
cortex, and anterior cingulate cortex is concerned with how nonhuman primates negotiate the …

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

MK Wittmann, E Fouragnan, D Folloni… - Nature …, 2020 - nature.com
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

D Meder, N Kolling, L Verhagen, MK Wittmann… - Nature …, 2017 - nature.com
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

PL Lockwood, MK Wittmann, MAJ Apps… - Nature …, 2018 - nature.com
Sense of ownership is a ubiquitous and fundamental aspect of human cognition. Here we
used model-based functional magnetic resonance imaging and a novel minimal ownership …

Polarity of uncertainty representation during exploration and exploitation in ventromedial prefrontal cortex

…, E Fouragnan, L Tankelevitch, MK Wittmann… - Nature Human …, 2021 - nature.com
Environments furnish multiple information sources for making predictions about future
events. Here we use behavioural modelling and functional magnetic resonance imaging to …
