Distributed activity in the human posterior putamen distinguishes goal-directed from habitual control

The paper uses fMRI decoding to show that neural activity in the posterior putamen during learning predicts individual differences in habit versus goal-directed behavior across multiple cohorts.

Model-based and model-free valuation signals in the human brain vary markedly in their relationship to individual differences in human behavioral control

The paper examines how model-based and model-free valuation signals in the human brain relate to individual differences in behavioral control using fMRI data from a large sample.

Temporally organized representations of reward and risk in the human brain

This study uses iEEG to show how reward and risk computations are temporally organized in the human brain, revealing cascading and parallel encoding patterns.

Neurons in human pre-supplementary motor area encode key computations for value-based choice

The paper investigates how neurons in the human pre-supplementary motor area (preSMA) encode decision variables during value-based choices, finding that preSMA neurons represent both separate pre-decision variables and an integrated utility signal.

Characterizing habit learning in the human brain at the individual and group levels: a multi-modal MRI study

This study attempts to replicate and extend findings on habit formation in humans using multi-modal MRI, but finds no clear habit formation with training duration and identifies goal-directed neural patterns instead.

Novelty and uncertainty interact to regulate the balance between exploration and exploitation in the human brain.

This study investigates how novelty and uncertainty influence exploration vs. exploitation in the human brain using a novel task and computational modeling.
