Charting vulnerability of brainstem functional pathways in aging and prodromal synucleinopathy

This study maps brainstem-cortical connectivity in aging and prodromal synucleinopathy, finding distinct pathway vulnerabilities in each condition.

Structure-function coupling in the human brainstem

This study reconstructs brainstem connectomes using MRI and finds structural and functional connectivity correlations, revealing heterogeneous structure-function coupling across brainstem nuclei.

Widespread gray and white matter microstructural alterations in dual cognitive-motor impairment

This study identifies widespread microstructural changes in gray and white matter in individuals with dual cognitive-motor impairment compared to isolated impairments and controls.

Integrating brainstem and cortical functional architectures

This study integrates brainstem and cortical functional architectures using fMRI, revealing brainstem hubs that connect to the cortex and influence cortical functional organization.

Neuronal microstructural changes in the human brain are associated with neurocognitive aging

This study uses diffusion MRI to identify microstructural changes in the human brain associated with neurocognitive aging, finding that microstructural markers are more strongly linked to cognitive performance than macrostructural changes.

Functional connectome of brainstem nuclei involved in autonomic, limbic, pain and sensory processing in living humans from 7 Tesla resting state fMRI

The paper constructs a functional connectome of brainstem nuclei in humans using 7 Tesla fMRI, confirming known pathways and showing translatability to 3 Tesla data.

Functional connectome of arousal and motor brainstem nuclei in living humans by 7 Tesla resting-state fMRI

The paper maps the functional connectivity of 18 arousal and motor brainstem nuclei in humans using 7 Tesla fMRI and validates its applicability to conventional 3 Tesla fMRI.

Probabilistic atlas of the lateral parabrachial nucleus, medial parabrachial nucleus, vestibular nuclei complex and medullary viscero-sensory-motor nuclei complex in living humans from 7 Tesla MRI

The paper creates a probabilistic brainstem atlas in living humans using 7 Tesla MRI to improve the localization of key nuclei for autonomic and sensory-motor functions.
