1. A method for approximating a target detection rate for a neurological event with a neurological event detector intended for use with a human patient, comprising:

  • identifying a target detection rate for the neurological event;

    monitoring electrographic signals incident on the neurological event detector;

    comparing each electrographic signal to a threshold value for a parameter the variation of which has a predictable effect on a detection rate of the neurological event;

    measuring a rate at which the electrographic signals exceed the threshold value to determine a measured detection rate;

    comparing the measured detection rate to the target detection rate; and

    adjusting the threshold value to minimize a difference between the measured detection rate and the target detection rate.
