The impact of ischemic stroke on connectivity gradients.
Şeyma Bayrak,Ahmed A. Khalil,Kersten Villringer,Jochen B. Fiebach,Arno Villringer,Daniel S. Margulies,Smadar Ovadia-Caro,Smadar Ovadia-Caro,Smadar Ovadia-Caro +8 more
TL;DR: It is demonstrated that ischemic strokes result in dimension-specific alterations in functional connectivity over the first week after symptom onset, and a novel framework to characterize connectivity alterations after stroke is suggested.
Journal ArticleDOI
Automated individual-level parcellation of Broca's region based on functional connectivity
Estrid Jakobsen,Franziskus Liem,Manousos A. Klados,Şeyma Bayrak,Michael Petrides,Daniel S. Margulies +5 more
TL;DR: While the current study focuses on Broca's region, the method is adaptable to parcellate other cortical regions with distinct connectivity profiles, and can be applied to resting‐state fMRI datasets with varying acquisition and preprocessing parameters.

The impact of ischemic stroke on connectivity gradients

TL;DR: This work defines a three-dimensional connectivity space template based on functional connectivity data from healthy controls and demonstrates that ischemic strokes resulted in dimension-specific alterations in functional connectivity over the first week after symptoms onset, and suggests that the indirect effects of isChemic strokes spread along the brain relative to the space defined by its connectivity.

Genetic and phylogenetic uncoupling of structure and function in human transmodal cortex
Sofie L. Valk,Ting Xu,Casey Paquola,Bo-yong Park,Richard A. I. Bethlehem,Vos de Wael R,Jessica Royer,Kharabian Masouleh S,Şeyma Bayrak,Peter Kochunov,Yeo Bt,Daniel S. Margulies,Smallwood J,Simon B. Eickhoff,Boris C. Bernhardt +14 more
TL;DR: In this paper, the authors synthesize genetic, phylogenetic and cognitive analyses to understand how the macroscale organization of structure-function coupling across the cortex can inform its role in cognition.
Journal ArticleDOI
Heritability of hippocampal functional and microstructural organisation
Şeyma Bayrak,Ramaraj Palanisamy +1 more
TL;DR: In this article , the authors studied how a heritable, stable, hippocampal organisation may support its flexible function in healthy adults, and demonstrated that structure and function couple along an inherited macro-scale organisation, suggesting an interplay of stability and plasticity within the hippocampus.
