Fractionation of sex differences in human cortical anatomy
Hyo Min Lee, Siyuan Liu, Elisa Guma…·Armin Raznahan
The paper quantifies sex differences in human cortical volume by separating contributions from surface area and thickness, and links these to genetic and hormonal factors using neuroimaging data.

The variegation of human brain vulnerability to rare genetic disorders and convergence with behaviorally defined disorders
Elizabeth Levitis, Siyuan Liu, Ethan T. Whitman…·Armin Raznahan
The paper examines how different gene dosage disorders affect the human brain using multimodal neuroimaging, revealing diverse cortical changes and a shared vulnerability axis aligned with psychiatric disorders.

Carriage of Supernumerary Sex Chromosomes Decreases the Volume and Alters the Shape of Limbic Structures.
Ajay Nadig, Paul Kirkpatrick Reardon, Jakob Seidlitz…·Armin Raznahan
This study examines how supernumerary sex chromosomes affect limbic structure volume and shape in patients compared to controls, finding reduced amygdala volume but no hippocampal volume changes after brain size correction.

Normative Brain Size Variation and the Remodeling of Brain Shape in Humans
Paul Kirkpatrick Reardon, Jakob Seidlitz, Simon Vandekar…·Armin Raznahan
The paper finds that larger-brained humans show preferential expansion of fronto-parietal cortical networks and related subcortical regions, at the expense of primary sensory/motor systems.

Morphometric Similarity Networks Detect Microscale Cortical Organisation And Predict Inter-Individual Cognitive Variation
Jakob Seidlitz, František Váša, Maxwell Shinn…·Edward Thomas Bullmore
The paper introduces morphometric similarity networks to map cortical organization and shows they predict cognitive variation across individuals.
