Feedback form is now closed.

Epilepsy is a brain disorder characterised by sudden, unexpected seizures which disrupt normal brain function. Patients often show abnormalities on EEG and MRI.
I will begin my talk with some observations on the spatio-temporal dynamics of epileptic seizures from intracranial EEG and present a simple dynamical (neural population) model that explain these observations.

I will continue to show that these observations must be refined to be clinically useful on an individual patient basis. To refine the observations, I will show some recent analyses of spatio-temporal dynamics during epileptic seizures, but also in the interictal periods between seizures in individual patients.

Our analyses demonstrate that spatio-temporal brain dynamics contain useful information to support clinical treatment of individual patients. However, to make this important translational step, I will argue that it will be crucial to consider patient-specific modulations that fluctuate on different time-scales.
