Mapping the topographic organization of the human zona incerta using diffusion MRI

This study maps the topographic organization of the human zona incerta using diffusion MRI and connectivity analysis, revealing gradients and clusters linked to specific cortical regions and functions.

Higher-order interdependencies of the epileptogenic network in presurgical resting-state fMRI

The paper uses multivariate information theory to analyze higher-order network interactions in drug-resistant focal epilepsy patients using resting-state fMRI, finding that redundant information-sharing dominates epileptogenic networks and correlates with surgical outcomes.

An anatomically distinct dopaminergic cell population of the zona incerta as evidence for the human A13 nucleus

The paper identifies a human zona incerta subregion with characteristics of the rodent A13 nucleus using MRI and histology.

Cholinergic synaptic plasticity shapes resilience and vulnerability to tau

The paper shows that cholinergic synaptic plasticity, specifically VAChT responses to tau, correlates with cognitive resilience in presymptomatic AD.

Multimodal gradients of basal forebrain connectivity across the neocortex

This study examines gradients of basal forebrain connectivity in the human cortex using multimodal imaging and finds reduced tethering between structural and functional connectivity in specific brain regions.

Focal acetylcholinergic modulation of the human midcingulo-insular network during attention: Meta-analytic neuroimaging and behavioral evidence

This study uses meta-analytic neuroimaging to show acetylcholine modulates midcingulo-insular network activity during attention, enhancing response speed without sacrificing accuracy.

Novel insights into hippocampal perfusion using high-resolution, multi-modal 7T MRI

This study measures hippocampal perfusion using 7T MRI and finds significant subfield differences, with CA1 having the lowest perfusion, influenced by vascular proximity and cytoarchitecture.
