Abstract
A method of monitoring neural activity responsive to a stimulus in a brain, the method comprising: applying the stimulus to one or more of at least one electrode implanted in a target neural structure of the brain; detecting a resonant response from the target neural structure evoked by the stimulus at one or more of the at least one electrode in or near the target neural structure of the brain; and determining one or more waveform characteristics of the detected resonant response.
Claims24
A method of monitoring neural activity in a brain of a patient, the method comprising:
- applying a plurality of stimuli to one or more electrodes implanted in or near a target neural structure of the brain, each of the plurality of stimuli applied at a different location in the brain;
- detecting a resonant response from the target neural structure evoked by each of the plurality of stimuli at one or more of the electrodes in or near the target neural structure of the brain;
- and
- comparing one or more waveform characteristics of each of the detected resonant responses.
A neurostimulation system, comprising:
- at least one electrode adapted for implantation in or near a target neural structure in the brain;
- a signal generator selectively coupled to one or more of the at least one electrode and configured to generate and apply a plurality of stimuli to one or more electrodes implanted in or near a target neural structure of the brain, each of the plurality of stimuli applied at a different location in the brain;
- a measurement device selectively coupled to one or more of the at least one electrode and configured to detect a plurality of resonant responses from the target neural structure, each of the plurality of resonant responses evoked by a respective one of the plurality of stimuli;
- a processing unit coupled to the measurement device and configured to compare one or more waveform characteristics of each of the detected resonant responses.
A non-transitory computer readable medium storing instructions executable by a processor to:
- cause a plurality of stimuli to be applied to the brain of a patient by one or more electrodes implanted in or near a target neural structure of the brain, each of the plurality of stimuli applied at a different location in the brain;
- receive a detected resonant response from the target neural structure evoked by each of the plurality of stimuli at one or more of the electrodes in or near the target neural structure of the brain;
- and
- compare one or more waveform characteristics of each of the detected resonant responses.
