Medial prefrontal cortex as an action-outcome predictor
TLDR
It is shown that a simple model based on standard learning rules can simulate and unify an unprecedented range of known effects in mPFC, and suggests a new view of the medial prefrontal cortex, as a region concerned with learning and predicting the likely outcomes of actions, whether good or bad.Abstract:
The medial prefrontal cortex (mPFC) and especially anterior cingulate cortex is central to higher cognitive function and many clinical disorders, yet its basic function remains in dispute. Various competing theories of mPFC have treated effects of errors, conflict, error likelihood, volatility and reward, using findings from neuroimaging and neurophysiology in humans and monkeys. No single theory has been able to reconcile and account for the variety of findings. Here we show that a simple model based on standard learning rules can simulate and unify an unprecedented range of known effects in mPFC. The model reinterprets many known effects and suggests a new view of mPFC, as a region concerned with learning and predicting the likely outcomes of actions, whether good or bad. Cognitive control at the neural level is then seen as a result of evaluating the probable and actual outcomes of one's actions.read more

Understanding cingulotomy’s therapeutic effect in OCD through computer models
TL;DR: In this article , the anterior cingulate cortex (ACC) is modelled using attractor networks, where activity patterns resistant to change denote the inability to switch to new patterns, which can reflect inflexible thinking patterns or behaviors.

Neurocomputational Models of Cognitive Control
TL;DR: A review of cognitive control models can be found in this article , where the authors highlight several prominent models that have made significant progress towards understanding the core principles of neural information processing and computation that are central to cognitive control.

Positive hysteresis in emotion recognition: Face processing visual regions are involved in perceptual persistence, which mediates interactions between anterior insula and medial prefrontal cortex
TL;DR: In this paper , the authors used dynamic transitions between emotional expressions and combined behavioral assessment with functional magnetic resonance imaging (fMRI) to investigate the underlying circuitry of perceptual hysteresis in facial emotion recognition.

Diminished Feedback Evaluation and Knowledge Updating Underlying Age-Related Differences in Choice Behavior During Feedback Learning.
TL;DR: In this article, the authors investigated the relation between learning-related neural processes and choice behavior during feedback learning in two age groups and found that less successful learning in older adults, as indicated by a lower learning rate, correspond with a higher tendency to switch to the other stimulus option, and with a reduced adaptation of this switch choice behavior following positive feedback.

TL;DR: This paper presents and proves in detail a convergence theorem forQ-learning based on that outlined in Watkins (1989), showing that Q-learning converges to the optimum action-values with probability 1 so long as all actions are repeatedly sampled in all states and the action- values are represented discretely.

The neural basis of human error processing: Reinforcement learning, dopamine, and the error-related negativity.
TL;DR: This paper presented a unified account of two neural systems concerned with the development and expression of adaptive behaviors: a mesencephalic dopamine system for reinforcement learning and a generic error-processing system associated with the anterior cingulate cortex.
