US10143842

1. A method for providing electrical stimulation to a user, as the user undergoes a set of events pertaining to neurological activity of the user within a time window, the method comprising: (3) (2)

providing an electrical stimulation device at a surface of a head region of the user; and

with the electrical stimulation device, providing an electrical stimulation session, characterized by a set of portions, to a brain region of the user in association with the time window, wherein providing the electrical stimulation session comprises: delivering a first portion of the set of portions of the electrical stimulation session to the brain region of the user in association with a first event of the set of events;

receiving, at a biosignal detection device, a signal stream characterizing a neurological state of the user;

detecting a second event, the second event comprising an entry of the user to a stressed state based on the signal stream; and

delivering a second portion of the set of portions of the electrical stimulation session to the brain region of the user upon detecting the second event.

2. The method of claim 1, wherein the signal stream comprises at least one electroencephalograph (EEG) signal, and wherein the biosignal detection device comprises an EEG sensor. (0)

3. The method of claim 1, further comprising providing the electrical stimulation session at a prefrontal cortex of the user, wherein the electrical stimulation session comprises anodal transcranial direct current stimulation. (0)

4. The method of claim 1, wherein the electrical stimulation session is characterized by a stimulation parameter, and further comprising providing at least one resting period between the first portion and the second portion of the electrical stimulation session, while maintaining an aggregate amount of the stimulation parameter of the electrical stimulation session provided to the user during the time window below a maximum limit. (0)

5. A method for providing electrical stimulation to a user comprising: (4) (5)

providing an electrical stimulation device at a head region of a user;

guiding the user in performing a task at a mobile computing device associated with the user;

determining a neurological state of the user associated with the performance of the task by the user, wherein determining the neurological state comprises determining an emotional state of the user;

at an electrical stimulation device, providing an electrical stimulation treatment to a brain region of the user; and

modulating the electrical stimulation treatment provided to the user based upon the neurological state, thereby modifying the emotional state of the user.

6. The method of claim 5, further comprising (7) (2)

at a biosignal detection device, receiving a signal stream characterizing the neurological state of the user; wherein receiving the signal stream comprises receiving signals contemporaneously with performance of the task by the user;

at a processing system coupled to the biosignal detection device, identifying a neurological signature indicative of the neurological state from the signal stream.

7. The method of claim 6, wherein the neurological state comprises a mental health state, and performance of the task comprises responding to a prompt rendered at the mobile computing device. (0)

8. The method of claim 6, wherein the signal stream comprises at least one electroencephalograph (EEG) signal, and wherein the biosignal detection device comprises an EEG sensor. (0)

9. The method of claim 6, further comprising receiving the signal stream within a time window, and modulating the electrical stimulation treatment within the time window, wherein an aggregated parameter of the electrical stimulation treatment provided to the user during the time window does not exceed a maximum limit. (1) (0)

11. The method of claim 6, wherein modulating comprises detecting at least one of an entrance and an exit of the neurological state at the biosignal detection device, and modulating the electrical stimulation treatment upon detection of at least one of the entrance and the exit of the neurological state. (0)

12. The method of claim 6, further comprising detecting desynchronization in neural oscillations of the user, and modulating the electrical stimulation treatment in association with the desynchronization and based on a metric associated with the performance of the task. (0)

13. The method of claim 6, wherein providing the electrical stimulation treatment comprises providing stimulation toward least at one of a frontal cortex region and a prefrontal cortex region of the user. (0)

14. The method of claim 6, wherein receiving the signal stream characterizing the neurological state comprises receiving signals indicative of a focus state of the user in association with performance of the task. (0)

15. The method of claim 5, wherein the task comprises a mental training activity, and wherein modulating the electrical stimulation treatment comprises modulating based upon the neurological state associated with the mental training activity. (0)

16. The method of claim 5, further comprising detecting an entry of the user to a pain state based on the performance of the task, and providing the electrical stimulation treatment upon detecting the entry of the user to the pain state. (0)

17. The method of claim 5, further comprising providing the electrical stimulation treatment at a prefrontal cortex of the user, wherein the electrical stimulation treatment comprises anodal transcranial direct current stimulation. (0)
