Giving you five: A neuroimaging atlas of the nigrosomes in the substantia nigra based on 3D histology

This paper creates a 3D histological atlas of nigrosomes in the substantia nigra aligned to MNI152 space, enabling MRI analysis of these structures in Parkinson's disease.

Subcortical nuclei of the human ascending arousal system encode anticipated reward but do not predict subsequent memory

The paper investigates subcortical nuclei activity during reward anticipation and memory encoding, finding increased activity during reward anticipation but no predictive effect on memory.

Multi-study fMRI outlooks on subcortical BOLD responses in the stop-signal paradigm

This study merges five fMRI datasets using a novel aggregatory method to analyze subcortical BOLD responses in the stop-signal paradigm, finding large subcortical activity for failed stops and highlighting the impact of smoothing on GLMs.

Joint models reveal human subcortical underpinnings of choice and learning behaviour

This study uses joint models to analyze human subcortical contributions to choice and learning, finding subcortical regions involved in decision urgency and reward prediction error processing.

The ageing stopping network: Regional and network changes in the IFG, preSMA, and STN across the adult lifespan

The paper examines anatomical changes in the response inhibition network across the adult lifespan using diffusion MRI and finds age-related changes in white matter tracts rather than regional structure.

Morphometrical asymmetries and tractography of speech-relevant cortex in relation to language lateralisation and rapid temporal processing

The paper examines associations between morphometrical and tractography measures of speech-related cortex and speech lateralisation and rapid temporal processing.

Investigating working memory updating processes of the human subcortex using 7T MRI

This study investigates subcortical involvement in working memory updating using 7T MRI and finds subcortical activation during gate closing and substitution, suggesting a role in general updating processes rather than specific gating.

Charting human subcortical maturation across the adult lifespan with in vivo 7 T MRI

This study maps age-related changes in 17 human subcortical structures using in vivo 7 T MRI, revealing shifts in location and properties across the adult lifespan.

No evidence for three functionally specialized subregions in the subthalamic nucleus: A model-based 7 T fMRI study

This study uses 7 T fMRI to test the tripartite model of subthalamic nucleus organization in healthy volunteers and finds no evidence for functionally distinct subregions.

A new model of decision processing in instrumental learning tasks

This paper introduces a new reinforcement learning-error accumulation model (RL-ARD) that better captures response time dynamics in instrumental learning tasks compared to existing models.

Multi-contrast Anatomical Subcortical Structures Parcellation

This paper introduces a new open-source algorithm for automatically parcellating subcortical structures in MRI data, validated against experts and tested on 17 structures.

3 versus 7 Tesla Magnetic Resonance Imaging for parcellations of subcortical brain structures

This study compares 3T and 7T MRI for parcellating subcortical brain structures, finding 7T provides better interrater agreement and contrast-to-noise ratios for smaller structures.

Outcome contingency selectively affects the neural coding of outcomes but not of tasks

The paper examines how outcome contingency affects neural coding of rewards and tasks using fMRI, finding enhanced reward coding but no task coding differences under contingency.

Denoising High-field Multi-dimensional MRI with Local Complex PCA

This paper introduces a denoising technique for multi-parametric quantitative MRI that improves signal-to-noise ratio without compromising spatial accuracy or creating spurious boundaries.

Cortico-basal white matter alterations occurring in Parkinson’s disease

This study assesses white matter alterations in Parkinson’s disease using diffusion tractography and age-specific anatomical atlases, finding decreased fractional anisotropy in specific brain connections.

The role of dopaminergic nuclei in predicting and experiencing gains and losses: A 7T human fMRI study

This study uses 7T fMRI to examine dopaminergic nuclei in humans, finding correlations with reward prediction error and risk in SN and VTA, and a surprise signal in SN.
