1. An implantable neurostimulator for the treatment of a neurological disorder, comprising:
- a detection subsystem including a plurality of detection channels that are configured to detect a neurological event of interest in a monitored electrographic signal of a patient, the plurality of detection channels including at least one triggering detection channel that is configured to derive signal timing for delivering a selected therapy when a parameter is detected, the parameter being associated with the triggering detection channel and corresponding to an electrographic measurement, a characteristic of the neurological event of interest being represented by the electrographic measurement;
a data storage area associated with the detection channels and configured to store the parameter that comprises the electrographic measurement; and
an adaptive stimulation subsystem configured to analyze the parameter, to select a therapy from a plurality of therapies based at least in part on the parameter, to determine a timing of the therapy based at least in part on the parameter, and to deliver the selected therapy to the patient in synchronization with the neurological event of interest based at least in part on the parameter.

Abstract
An implantable neurostimulator system adapted to provide therapy for various neurological disorders is capable of varying therapy delivery strategies based on the context, physiological or otherwise, into which the therapy is to be delivered. Responsive and scheduled therapies can be varied depending on various sensor measurements, calculations, inferences, and device states (including elapsed times and times of day) to deliver an appropriate course of therapy under the circumstances.
