Closed-loop feedback-driven neuromodulation
First Claim
1. A method of treating a patient'"'"'s neurological or psychiatric disorder, the method comprising:
- using a control module coupled to a first electrode and a second electrode to deliver electrical stimulation to a nervous system component through the first electrode and the second electrode to treat the patient'"'"'s neurological or psychiatric disorder, said first electrode and said second electrode being implanted in the patient'"'"'s body;
monitoring impedance between the first electrode and the second electrode;
automatically adjusting at least one parameter of the electrical stimulation to compensate for a monitored change of electrode impedance between the first electrode and the second electrode; and
delivering a subsequent electrical stimulation with the at least one adjusted parameter to the nervous system component through the first electrode and the second electrode to treat the patient'"'"'s neurological or psychiatric disorder.

Abstract
A neurological control system for modulating activity of any component or structure comprising the entirety or portion of the nervous system, or any structure interfaced thereto, generally referred to herein as a “nervous system component.” The neurological control system generates neural modulation signals delivered to a nervous system component through one or more neuromodulators, comprising intracranial (IC) stimulating electrodes and other actuators, in accordance with treatment parameters. Such treatment parameters may be derived from a neural response to previously delivered neural modulation signals sensed by one or more sensors, each configured to sense a particular characteristic indicative of a neurological or psychiatric condition.
