1. An apparatus for monitoring and treating seizure activity from electroencephalogram, the apparatus comprising:

  • a first electrode providing a first temporal signal and a second electrode providing a second temporal signal from a brain of a subject;

    a digital processing unit performing steps comprising;

    computing a cross-power spectral density for a band of frequencies using the first and second temporal signals;

    computing a second cross-power spectral density for a second band of frequencies;

    determining a ratio of the first cross-power spectral density to the second cross-power spectral density; and

    using the ratio to determine the seizure status of the subject; and

    in response to the seizure status of the subject, triggering delivery of a seizure treatment to the subject.
