How infant brains fold: Sulcal deepening is linked to development of sulcal span, thickness, curvature, and microstructure Open

Sarah Tung, Xiaoqian Yan, Bella Fascendini, Christina Tyagi, Charleny Martinez Reyes , et al. · 2025

Cortical folding begins in utero as sulci emerge and continues postnatally as sulci deepen. However, the timeline and mechanisms underlying postnatal sulcal development remain unknown. Using structural and quantitative magnetic resonance i…

Superior temporal sulcus folding, functional network connectivity, and autistic-like traits in a non-clinical population Open

Igor Nenadić, Yvonne Schröder, Jonas Hoffmann, Ulrika Evermann, Julia‐Katharina Pfarr , et al. · 2024

Background Autistic-like traits (ALT) are prevalent across the general population and might be linked to some facets of a broader autism spectrum disorder (ASD) phenotype. Recent studies suggest an association of these traits with both gen…

White matter connections of human ventral temporal cortex are organized by cytoarchitecture, eccentricity, and category-selectivity from birth Open

Emily C. Kubota, Xiaoqian Yan, Sarah Tung, Bella Fascendini, Christina Tyagi , et al. · 2024

Category-selective regions in ventral temporal cortex (VTC) have a consistent anatomical organization, which is hypothesized to be scaffolded by white matter connections. However, it is unknown how white matter connections are organized fr…

The connectivity-based architecture of the human piriform cortex Open

Felix Zahnert, Urs Kleinholdermann, Marcus Belke, Boris Keil, Katja Menzler , et al. · 2024

The anatomy of the human piriform cortex (PC) is poorly understood. We used a bimodal connectivity-based-parcellation approach to investigate subregions of the PC and its connectional differentiation from the amygdala. One hundred (55 % fe…
