The Genetic and Environmental Architecture of the Human Functional Connectome
Tanu Raghav, Daniel Guerrero, Uttara Tipnis +8
Functional connectivity varies across individuals due to genetic and environmental factors, yet classical twin models typically confound non-shared environment with measurement err…
Stabilizing Fractional Dynamical Networks Suppresses Epileptic Seizures
Yaoyue Wang, Arian Ashourvan, Guilherme Ramos +2
Medically uncontrolled epileptic seizures affect nearly 15 million people worldwide, resulting in enormous economic and psychological burdens. Treatment of medically refractory epi…
A Linear Generative Framework for Structure-Function Coupling in the Human Brain
Sam Frank Kelemen, Joaquín Gõni, Sérgio Pequito +1
Brain function emerges from coordinated activity across anatomically connected regions, where structural connectivity (SC) -- the network of white matter pathways - provides the ph…
Shifts in Brain Dynamics and Drivers of Consciousness State Transitions
Joseph Bodenheimer, Paul Bogdan, Sérgio Pequito +1
Understanding the neural mechanisms underlying the transitions between different states of consciousness is a fundamental challenge in neuroscience. Thus, we investigate the underl…
Spontaneous brain activity emerges from pairwise interactions in the larval zebrafish brain
Richard E. Rosch, Dominic R. W. Burrows, Christopher W. Lynn +1
Brain activity is characterized by brain-wide spatiotemporal patterns which emerge from synapse-mediated interactions between individual neurons. Calcium imaging provides access to…
Time-evolving controllability of effective connectivity networks during seizure progression
Brittany H. Scheid, Arian Ashourvan, Jennifer Stiso +5
Over one third of the estimated 3 million people with epilepsy in the US are medication resistant. Responsive neurostimulation from chronically implanted electrodes provides a prom…
Temporal sequences of brain activity at rest are constrained by white matter structure and modulated by cognitive demands
Eli J. Cornblath, Arian Ashourvan, Jason Z. Kim +13
A diverse white matter network and finely tuned neuronal membrane properties allow the brain to transition seamlessly between cognitive states. However, it remains unclear how stat…
Parsing spatiotemporal dynamical stability in ECoG during seizure onset, propagation, and termination
Arian Ashourvan, Sérgio Pequito, Ankit N. Khambhati +7
Understanding brain dynamics in epilepsy is critical for establishing rigorous control objectives that enable new therapeutic methods to mitigate seizure occurrence. In multichanne…
Multi-scale detection of hierarchical community architecture in structural and functional brain networks
Arian Ashourvan, Qawi K. Telesford, Timothy Verstynen +2
Community detection algorithms have been widely used to study the organization of complex systems like the brain. A principal appeal of these techniques is their ability to identif…
The Energy Landscape Underpinning Module Dynamics in the Human Brain Connectome
Arian Ashourvan, Shi Gu, Marcelo G. Mattar +2
Human brain dynamics can be profitably viewed through the lens of statistical mechanics, where neurophysiological activity evolves around and between local attractors representing…
