This study shows that disrupting the mediodorsal thalamus with focused ultrasound reduces decision flexibility during reward learning in patients with essential tremor.

This study investigates decision-making impairments in Parkinson's disease patients with apathy using reinforcement learning tasks and fMRI, finding reduced value-based choices and distinct neural activation patterns.

This study shows that neuromodulation of the globus pallidus interna affects exploration in decision-making tasks by altering evidence accumulation rates.

This paper presents a computational model of the basal ganglia that shows tonic dopamine modulates explore-exploit decision making by affecting action selection precision under uncertainty.

The paper shows that increased risk-taking in DYT1 dystonia patients is explained by a model with opposing D1 and D2 receptor-dependent cortico-striatal plasticity abnormalities.

This study investigates abnormal reward-learning in cervical dystonia using computational modeling and finds that decreased D2 cortico-striatal synaptic plasticity explains impaired reversal learning.
