Non-homogeneous multichannel electroencephalographic dynamic forward modeling of epilepsy

Abstract

This paper shows signals of brain activity per zones, which were obtained through a dynamic forward model that considers non- homogeneous temporal activity in a group of regions. This activity could be observed in a multichannel electroencephalography. The forward model combines the reduction of source space and a model of spatio-temporal propagation of neural activity, in which the independent non-homogeneous brain activity is introduced for each zone. This model allowed us to simulate brain activity similar to epilepsy in a specific area, which could be observed in the multichannel electroencephalography, and is therefore a first step to carry on a focused analysis of the brain activity and the inter-connectivity among zones.
