Mapping Higher-Order Topology in OCD Brain Networks with Hodge Laplacian

Hanyang Ruan, Moo K Chung, Willem B. Bruin, Nadža Džinalija, Yoshinari Abe, P. Alonso, Alan Anticevic, Srinivas Balachander, Marcelo C. Batistuzzo, Francesco Benedetti, Sara Bertolín, Silvia Brem, Youngsun Cho, Federica Colombo, Beatriz Couto, , Kathrin Koch

This paper introduces a Hodge-Laplacian framework to analyze higher-order topology in OCD brain networks, identifying loop-level abnormalities not detectable by conventional functional connectivity analysis.

Neuroanatomical Correlates of Negative Symptoms in Schizophrenia

SO M Vijayakumar Kamalakannan, Alie G. Male, Musa Yilanli, Annalisa Lella, Jaylen Lee, Yann Quidé, Melissa J. Green, Murray J. Cairns, Vaughan J. Carr, Stanley Victor Catts, Frans Alexander Henskens, Assen V Jablensky, Carmel Maree Loughland, Patricia Therese Michie, Bryan J. Mowry, , Theo G.M. van Erp

This study identifies small but consistent anatomical correlates of negative symptom dimensions in schizophrenia, linking them to prefrontal cortical thickness and limbic subcortical volumes.
