Long-term changes in functional connectivity predict responses to intracranial stimulation of the human brain
Christoforos Papasavvas, Peter Neal Taylor, Yujiang Wang
Targeted electrical stimulation of the brain perturbs neural networks and modulates their rhythmic activity both at the site of stimulation and at remote brain regions. Understandi…
Local Morphological Measures Confirm that Folding within Small Partitions of the Human Cortex Follows Universal Scaling Law
Karoline Leiberg, Christoforos Papasavvas, Yujiang Wang
The universal scaling law of cortical morphology describes cortical folding as the covariance of average grey matter thickness, pial surface area, and exposed surface area. It appl…
Gain modulation unlocks phase plasticity, thus allowing for malleable nonlinear dynamics
Christoforos Papasavvas
Nonlinear dynamics emerge through either nonlinear interactions between the variables or through nonlinearities imposed on their linear interactions. Their interactions can be conc…
Fluctuations in EEG band power at subject-specific timescales over minutes to days explain changes in seizure evolutions
Mariella Panagiotopoulou, Christoforos A Papasavvas, Gabrielle M Schroeder +3
Epilepsy is recognised as a dynamic disease, where both seizure susceptibility and seizure characteristics themselves change over time. Specifically, we recently quantified the var…
Band power modulation through intracranial EEG stimulation and its cross-session consistency
Christoforos A Papasavvas, Gabrielle M Schroeder, Beate Diehl +3
Background: Direct electrical stimulation of the brain through intracranial electrodes is currently used to probe the epileptic brain as part of pre-surgical evaluation, and it is…
