Results for an epileptic EEG recording.

Abstract

<p>Matrices of causalities reflect before (top) and during (down) the clinical onset of a seizure from an epileptic patient, the results are respectively averaged from 8 recordings. Contacts 1 to 64 belong to a cortical electrode grid, and contacts 65 to 76 to two depth electrode strips. The values are computed by traditional non-uniform transfer entropy (TE) and low-dimensional approximation approach (LA). The directions of causal influence are from row to column. The brighter colors correspond to more significant values.</p
