Adolescence is associated with genomically patterned consolidation of the hubs of the human brain connectome
…, N Weiskopf, MF Callaghan… - Proceedings of the …, 2016 - National Acad Sciences
How does human brain structure mature during adolescence? We used MRI to measure
cortical thickness and intracortical myelination in 297 population volunteers aged 14–24 y old. …

Locus coeruleus imaging as a biomarker for noradrenergic dysfunction in neurodegenerative diseases
Pathological alterations to the locus coeruleus, the major source of noradrenaline in the
brain, are histologically evident in early stages of neurodegenerative diseases. Novel MRI …

A general linear relaxometry model of R1 using imaging data
Purpose The longitudinal relaxation rate (R 1 ) measured in vivo depends on the local
microstructural properties of the tissue, such as macromolecular, iron, and water content. Here, we …

Locus coeruleus integrity in old age is selectively related to memories linked with salient negative events
D Hämmerer, MF Callaghan… - Proceedings of the …, 2018 - National Acad Sciences
The locus coeruleus (LC) is the principal origin of noradrenaline in the brain. LC integrity
varies considerably across healthy older individuals, and is suggested to contribute to altered …
