1. A method for treating an abnormal neurological condition comprising: detecting an electrical signal in brain tissue prior to initiating application of at least one electrical burst; determining an interval of the electrical signal in the brain tissue prior to initiating the application of the at least one electrical burst; and delaying initiation of the application of the at least one electrical burst after the onset of the detected electrical signal for a period of time corresponding to a range of between 5% and about 100% of the interval of the electrical signal.
