Unification of neuronal spikes, seizures, and spreading depression

Y Wei, G Ullah, SJ Schiff - Journal of Neuroscience, 2014 - Soc Neuroscience
The pathological phenomena of seizures and spreading depression have long been
considered separate physiological events in the brain. By incorporating conservation of …

Predicting the spatiotemporal diversity of seizure propagation and termination in human focal epilepsy

T Proix, VK Jirsa, F Bartolomei, M Guye… - Nature …, 2018 - nature.com
Recent studies have shown that seizures can spread and terminate across brain areas via a
rich diversity of spatiotemporal patterns. In particular, while the location of the seizure onset …

Ionic and synaptic mechanisms of seizure generation and epileptogenesis

OC González, GP Krishnan, I Timofeev… - Neurobiology of …, 2019 - Elsevier
The biophysical mechanisms underlying epileptogenesis and the generation of seizures
remain to be better understood. Among many factors triggering epileptogenesis are …

Mechanisms underlying pathological cortical bursts during metabolic depletion

S Dutta, KK Iyer, S Vanhatalo, M Breakspear… - Nature …, 2023 - nature.com
Cortical activity depends upon a continuous supply of oxygen and other metabolic
resources. Perinatal disruption of oxygen availability is a common clinical scenario in …

The role of cell volume in the dynamics of seizure, spreading depression, and anoxic depolarization

G Ullah, Y Wei, MA Dahlem… - PLoS computational …, 2015 - journals.plos.org
Cell volume changes are ubiquitous in normal and pathological activity of the brain.
Nevertheless, we know little of how cell volume affects neuronal dynamics. We here …

Origin of slow spontaneous resting-state neuronal fluctuations in brain networks

GP Krishnan, OC González… - Proceedings of the …, 2018 - National Acad Sciences
Resting-or baseline-state low-frequency (0.01–0.2 Hz) brain activity is observed in fMRI,
EEG, and local field potential recordings. These fluctuations were found to be correlated …

Modeling focal epileptic activity in the Wilson–Cowan model with depolarization block
