Journal ArticleDOI
Studying the human brain anatomical network via diffusion-weighted MRI and Graph Theory
Yasser Iturria-Medina,Roberto C. Sotero,Erick J. Canales-Rodríguez,Yasser Alemán-Gómez,Lester Melie-Garcia +4 more
TL;DR: In a vulnerability and betweenness centrality analysis, the most indispensable and critical anatomical areas were identified: putamens, precuneus, insulas, superior parietals and superior frontals, which suggest that even at the cost of losing in global anatomical efficiency, these structures were maintained through the evolutionary processes due to their important functions.
Journal ArticleDOI
Characterizing brain anatomical connections using diffusion weighted MRI and graph theory.
Yasser Iturria-Medina,Erick J. Canales-Rodríguez,Lester Melie-Garcia,Pedro A. Valdés-Hernández,Eduardo Martínez-Montes,Yasser Alemán-Gómez,Jose M. Sanchez-Bornot +6 more
TL;DR: A new methodology based on Diffusion Weighted Magnetic Resonance Imaging (DW-MRI) and Graph Theory is presented for characterizing the anatomical connections between brain gray matter areas, showing that nervous fiber pathways between some regions of interest were reconstructed correctly.
Journal ArticleDOI
Model driven EEG/fMRI fusion of brain oscillations
Pedro A. Valdes-Sosa,Jose M. Sanchez-Bornot,Roberto C. Sotero,Yasser Iturria-Medina,Yasser Alemán-Gómez,Jorge Bosch-Bayard,Felix Carbonell,T. Ozaki +7 more
TL;DR: For model driven fusion, a neural mass EEG/fMRI model coupled to a metabolic hemodynamic model is formulated, and it is shown that the Local Linearization (LL) method for integrating stochastic differential equations is appropriate for highly nonlinear dynamics.
Journal ArticleDOI
Surface area and cortical thickness descriptors reveal different attributes of the structural human brain networks.
Gretel Sanabria-Diaz,Lester Melie-Garcia,Yasser Iturria-Medina,Yasser Alemán-Gómez,Gertrudis Hernandez-Gonzalez,Lourdes Valdés-Urrutia,Lídice Galán,Pedro A. Valdes-Sosa +7 more
TL;DR: The surface area is employed as a morphometric descriptor to study the concurrent changes between brain structures and to build binarized connectivity graphs and it is demonstrated that connectivity matrices obtained follow a small-world behavior for two different parcellations of the brain gray matter.
Journal ArticleDOI
White matter microstructure correlates of mathematical giftedness and intelligence quotient
Francisco J. Navas-Sánchez,Yasser Alemán-Gómez,Javier Sánchez-González,Juan A Guzmán-De-Villoria,Carolina Franco,Olalla Robles,Celso Arango,Manuel Desco,Manuel Desco +8 more
TL;DR: Investigating the relationship between mathematical giftedness, intelligent quotient (IQ), and the microstructure of white matter tracts in a sample of math‐gifted adolescents and aged‐matched controls found IQ showed a significant positive correlation with FA, supporting the idea that efficient information transfer between hemispheres is crucial for higher intellectual capabilities.
