In this paper we assess a dependency measure for

multivariate time series termed Extrinsic-to-Intrinsic-Power-

Ratio (EIPR) using two different signal models. In a comparison

with Partial Directed Coherence (PDC) we show that both measures

correctly identify imposed couplings, but that limitations

of the PDC do not affect EIPR. Moreover, EIPR is successfully

used for the detection of the seizure zone in ECoG recordings

from two epilepsy patients. The electrodes identified by the

proposed method are in excellent accordance with the clinical

findings.
