Claim:
1. A neurostimulation device, comprising: a plurality of electrodes adapted to be electrically connected to a subject to receive multichannel electrical signals from a brain of said subject; a multichannel seizure detection unit electrically connected to said plurality of electrodes to receive said multichannel electrical signals; and a neurostimulation unit in communication with said multichannel seizure detection unit, wherein said plurality of electrodes are at least three electrodes such that said multichannel electrical signals are at least three channels of electrical signals, wherein said multichannel seizure detection unit detects a presence of a seizure based on multichannel statistics from said multichannel electrical signals including higher order combinations than two-channel combinations, wherein said multichannel seizure detection unit is configured to detect said presence of said seizure based on optimizing a cost function, and wherein said cost function is dependent on a time delay between an actual seizure and a prediction of said seizure.
