Dopamine role in learning and action inference
- Psychology, BiologybioRxiv
- 2019
Dopaminergic neurons projecting to different parts of the striatum encode errors in predictions made by the corresponding systems within the basal ganglia, which enable learning about rewards resulting from actions and habit formation.
Beyond Simple Tests of Value: A neuroeconomic, translational, disease-relevant, and circuit-based approach to resolve the computational complexity of decision making
- Computer Science
- 2018
This dissertation presents a meta-anatomy of the central nervous system and its role in reward and punishment and describes its role as a “spatially aggregating force” in the response to disease.

Reward Prediction Errors Reflect an Underlying Learning Process That Parallels Behavioural Adaptations: A Trial-to-Trial Analysis
- Psychology, BiologyComputational Brain & Behavior
- 2019
It is found that neural measures did diminish with trial-to-trial changes in performance and that they were predictive of behavioural adaptations in both simulated and empirical data.

An economic decision-making model of anticipated surprise with dynamic expectation

When making decisions under risk, people often exhibit behaviors that classical economic theories cannot explain. Newer models that attempt to account for these ‘irrational’ behaviors often lack…
Feature Specific Prediction Errors and Surprise across Macaque Fronto-Striatal Circuits during Attention and Learning
- Biology, PsychologybioRxiv
- 2018
It is shown that neurons in all areas of the medial and lateral fronto-striatal networks encode prediction errors that are specific to separate features of attended multidimensional stimuli, with the most ubiquitous prediction error occurring for the reward relevant features.
VTA dopamine neuron activity encodes social interaction and promotes reinforcement learning through social prediction error
- Psychology, BiologyNature neuroscience
- 2021
This study shows that dopamine neurons of the ventral tegmental area of the VTA increase their activity during interactions with an unfamiliar conspecific and display heterogeneous responses, and suggests that VTA DA neurons are a neural substrate for a social learning signal that drives motivated behavior.
Behavioural variability and cortical electrophysiological signals depend on recent outcomes during human reinforcement motor learning
- Psychology, BiologybioRxiv
- 2021
The results suggest that S+ experiences ‘overwrite’ previous motor states to a greater extent than S- experiences and that modulations in neural oscillations in the prefrontal cortex play a potential role in encoding the (changes in) movement variability state during reinforcement motor learning.

Dopamine reward prediction-error signalling: a two-component response
- Psychology, BiologyNature Reviews Neuroscience
- 2016
It is suggested that an initial brief, unselective and highly sensitive increase in activity unspecifically detects a wide range of environmental stimuli, then quickly evolves into the main response component, which reflects subjective reward value and utility.

The application of such quantitative models has opened up new fields, ripe for attack by young synthesizers and theoreticians, to describe the biological algorithms at play in their brains when the authors form value judgements and make choices.
A Neural Correlate of Reward-Based Behavioral Learning in Caudate Nucleus: A Functional Magnetic Resonance Imaging Study of a Stochastic Decision Task
- Biology, PsychologyThe Journal of Neuroscience
- 2004
Functional magnetic resonance imaging of a stochastic decision task involving monetary rewards, in which subjects had to learn behaviors involving different task difficulties that were controlled by probability, found that activity in the caudate nucleus was correlated with short-term reward and paralleled the magnitude of a subject's behavioral change during learning.

D dopamine neurons responded to liquid reward during learning but not when task performance was established, at which time the neuronal response occurred to the conditioned, reward-predicting, movement-triggering stimulus.
