1. A method for treating an abnormal neurological condition comprising:
- applying a plurality of bursts of electrical stimulation to brain tissue, wherein each burst of the plurality of bursts comprises a determined number of electrical pulses, the plurality of bursts being characterizable by a plurality of burst parameters;
varying at least one of the burst parameters of the plurality of burst parameters during at least a portion of the time the plurality of bursts of electrical stimulation is applied to vary the bursts so that the burst parameters of at least one burst of the plurality of bursts are different from the burst parameters of at least one other burst; and
synchronizing the applying of the plurality of bursts of electrical stimulation to the brain tissue with a detection of electrical activity of the brain tissue.

Abstract
This is a neurostimulator that is configured to treat epilepsy and other neurological disorders using certain stimulation strategies, particularly changing various pulse parameters, during the imposition of a burst of those pulses. The invention includes the processes embodying those stimulation strategies.

4. A method for treating an abnormal neurological condition comprising:
-
determining an interval of an electrical signal in brain tissue; and applying a plurality of bursts of electrical stimulation to the brain tissue, wherein each burst of the plurality of bursts comprises a determined number of electrical pulses, wherein the plurality of bursts are characterizable by a plurality of burst parameters, and wherein the electrical pulses have at least one pulse parameter related to the interval of the electrical signal in the brain tissue; and varying at least one of the burst parameters of the plurality of burst parameters during at least a portion of the time the plurality of bursts of electrical stimulation is applied to vary the bursts so that the burst parameters of at least one burst of the plurality of bursts are different from the burst parameters of at least one other burst. - View Dependent Claims (5, 6)
