The paper shows that SNr and FEF encode different aspects of decision-making: SNr reflects ordinal rank, while FEF reflects categorical commitment, supporting a division of labor in neural circuits.

This study identifies three functionally distinct STN neuron populations in macaques during a value-based task, showing that two primarily encode stimulus value and precede GPe activity.

This paper develops a 24-channel 3T RF coil for fMRI in awake monkeys, improving ferumoxytol-weighted functional connectivity estimation and identifying human-like functional networks.

This study investigates the role of the primate globus pallidus external segment in action initiation and suppression using single-unit recordings in macaques, identifying distinct neuronal clusters with facilitatory and inhibitory functions.

This study investigates how SNr neurons in macaques modulate activity to facilitate and suppress actions, showing that glutamatergic inputs are critical for suppression.

The paper identifies neurons in the anterior striatum of macaques involved in proactive inhibition during a decision-making task.

This study investigates the opposing roles of glutamatergic inputs to the GPe and SNr in basal ganglia function using behavioral tasks in monkeys.

This study uses quantitative susceptibility mapping (QSM) to better visualize subcortical structures in non-human primates, showing improved contrast-to-noise ratios and age-related changes.

This study compares cortico-subcortical functional connectivity in marmosets and humans using resting-state fMRI, finding both similarities and species-specific differences in network patterns.

The paper develops a 24-channel MRI coil and adapts HCP protocols for macaques, enabling high-quality in vivo imaging and preprocessing comparable to human studies.
