TLDR
Boosting dopamine enhances the dominance of action over valence in the striatum and dopaminergic midbrain and decreases the extent of the behavioral coupling between action and valence.About:

The theory of constructed emotion: an active inference account of interoception and categorization.
TL;DR: This article begins with the structure and function of the brain, and from there deduce what the biological basis of emotions might be, and concludes that the answer is a brain-based, computational account called the theory of constructed emotion.

TL;DR: The results suggest that the hippocampus is crucial for social cognition, and imply that beyond framing physical locations, the hippocampus computes a more general, inclusive, abstract, and multidimensional cognitive map consistent with its role in episodic memory.
Journal ArticleDOI
An active inference theory of allostasis and interoception in depression
TL;DR: It is speculated that depression is a disorder of allostasis, whose myriad symptoms result from a ‘locked in’ brain that is relatively insensitive to its sensory context, and a biologically plausible unified theory of the mind is proposed.

Revealing Neurocomputational Mechanisms of Reinforcement Learning and Decision-Making With the hBayesDM Package.
TL;DR: An R package called hBayesDM (hierarchical Bayesian modeling of Decision-Making tasks), which offers computational modeling of an array of RLDM tasks and social exchange games and is extremely user-friendly.

A Neural Substrate of Prediction and Reward
TL;DR: Findings in this work indicate that dopaminergic neurons in the primate whose fluctuating output apparently signals changes or errors in the predictions of future salient and rewarding events can be understood through quantitative theories of adaptive optimizing control.

Précis of The Neuropsychology of Anxiety: An Enquiry into the Functions of the Septo-Hippocampal System..
TL;DR: It is proposed that these drugs reduce anxiety by impairing the functioning of a widespread neural system including the septo-hippocampal system (SHS), the Papez circuit, the prefrontal cortex, and ascending monoaminergic and cholinergic pathways which innervate these forebrain structures.

Neuronlike adaptive elements that can solve difficult learning control problems
TL;DR: In this article, a system consisting of two neuron-like adaptive elements can solve a difficult learning control problem, where the task is to balance a pole that is hinged to a movable cart by applying forces to the cart base.

TL;DR: It is shown that human functional and structural imaging results map increasingly close to primate anatomy, and advances in neuroimaging techniques allow better spatial and temporal resolution.

Contributions of the Amygdala to Emotion Processing: From Animal Models to Human Behavior
TL;DR: Five major research topics are highlighted that illustrate parallel roles for the amygdala in humans and other animals, including implicit emotional learning and memory, emotional modulation of memory,otional influences on attention and perception, emotion and social behavior, and emotion inhibition and regulation.
