Abstract
Exemplary embodiments described herein provide systems and methods for administer multiple stimulus to a patient in order to improve the efficacy of the administered stimulus on the brain activity of the patient. Exemplary embodiments described herein may combined magnetic stimulation along with sensory stimulation to influence the intrinsic frequency of an EEG band of a person.
Claims19
A device comprising:
- at least one permanent magnet having a rhythmic movement with a rhythmic movement frequency;
- at least one light having a rhythmically changing intensity with an intensity frequency;
- a controller coupled to the magnet and to the light;
- wherein the controller comprises a processor that controls the rhythmic movement frequency of said at least one magnet between about 0.5 Hz and 100 Hz based on an intrinsic frequency of a brain of a subject within a specified EEG band;
- and controls the intensity frequency of at least one light set about equal to the rhythmic movement frequency, or a harmonic or subharmonic frequency thereof.
2 more elements
A device comprising:
- at least one magnetic field generator having a programmable pulse frequency;
- at least one light having a rhythmically changing intensity with an intensity frequency;
- and
- a controller coupled to the pulse generator and to the light;
- wherein the controller comprises a processor that controls the pulse frequency between about 0.5 Hz and 100 Hz based on an intrinsic frequency of a brain of a subject within a specified EEG band;
- and controls the intensity frequency of at least one light set about equal to the pulse frequency, or a harmonic or subharmonic thereof.
3 more elements
A device comprising:
- a controller comprising a processor, an EEG amplifier, and memory;
- a first electrode configured to detect electrical brain activity and coupled to the controller;
- a second electrode configured to detect a reference signal and coupled to the controller;
- wherein the controller is configured to generate and provide a stimulus to subject through rhythmic stimulation frequencies in or around a desired EEG band;
- determine an optimal rhythmic stimulation frequency which optimizes an aspect of an EEG spectrum recorded while the stimulus is being delivered;
- estimate the intrinsic frequency of the EEG band based on EEG data received from the subject.
