Abstract

This invention concerns a method for altering an individual'"'"'s level of consciousness by directing stimulation or inhibition to a CNS locus target region in the individual'"'"'s brain that is responsible for consciousness.

Claims

1. A method for altering an individual'"'"'s level of consciousness by directing stimulation or inhibition to a CNS locus target region in the individual'"'"'s brain that is responsible for consciousness.

2. The method according to claim 1, wherein the said target region is the ACC, cuneus, precuneus, prefrontal cortex, thalamus, hypothalamus, brainstem arousal areas such as the LC, or the parietal cortex, such as the intentional movement area.

3. The method according to claim 1, wherein the target region is a deeply located structure in the brain, such as ACC, and the stimulation is either

a direct excitatory or inhibitory stimulation of the deeply located structure, such as ACC, or

an excitatory or inhibitory stimulation of a superficial structure connected to the deeply located structure, to induce change in activity in the deeply located structure.

4. The method according to claim 3, wherein the superficial structure is a cortical area, such as the premotor cortex.

5. The method according to claim 3, wherein the superficial structure is sensory-motor/parietal cortex, in particular the parietal cortex intentional movement area.

6. The method according to claim 3, wherein several targets are stimulated and/or inhibited at the same time.

7. The method according to claim 3, wherein the superficial structure is superior fontal gyms or middle frontal gyrus.

8. The method according to claim 1, wherein the stimulation is TMS, optionally by using an H-coil or another specially designed coil in case deeply located regions shall be targeted.

9. The method according to claim 1, wherein the stimulation is audio stimulation, US, vestibular stimulation, nasal stimulation, focused laser beams, any form of electromagnetic radiation, light, heat and microwave to make a neuron fire.

10. The method according to claim 1, wherein the individual'"'"'s consciousness is returned from a state of anesthesia, sedation, sleep, coma, vegetative state, and minimally conscious state.

11. The method according to claim 10, wherein the ROC is caused by inhibitory (<

1 Hz) and/or excitatory TMS-stimulation (>

5 Hz).

12. The method according to claim 1, wherein the level of consciousness is decreased.

13. The method according to claim 12, wherein the decrease of consciousness is caused by inhibitory (<

1 Hz) and/or excitatory TMS-stimulation (>

5 Hz).

14. The method according to claim 1, wherein the method additionally comprises determining of at least one target region in the individual'"'"'s brain.

15. The method according to claim 14, wherein at least one target region in the individual'"'"'s brain is determined by a non-functional method carried out in a separate session before initiating the stimulation.

16. The method according to claim 15, wherein the non-functional method is anatomical MRI or DTI MRI.

17. The method according to claim 14, wherein the step of determining includes obtaining a brain map of the brain using other methods.

18. The method of claim 17, wherein the brain map is obtained using at least one of fMRI and other MRI based methods, PET, SPECT, qEEG, MEG, US, NIRS and other optical methods, CT and EIT.
