Adaptive tracking of EEG oscillations

Jean-Marc Vesin, Cédric Duchene, Yann Prudat, Laurent Renaud Uldry, Jérôme Sébastien Van Zaen

Neuronal oscillations are an important aspect of EEG recordings. These oscillations are supposed to be involved in several cognitive mechanisms. For instance, oscillatory activity is considered a key component for the top-down control of perception. Howeve ...

Activity Level of an Atrial Ectopic Focus Observed Through the Equivalent Dipole: a Biophysical Model

Jean-Marc Vesin, Vincent Jacquemet, Mathieu Lemay, Cédric Duchene

Quantifying the role of atrial ectopic foci in the initiation and the maintenance of atrial fibrillation (AF) is a relevant clinical problem. This study aims at assessing the relation between the activity level of an ectopic focus and the complexity of the ...
