Classification: CPC A  G | IPC A

Claim 9:
10. A system for neurosensing and stimulation, comprising:
a headset configured to be worn on a forehead of a user, the headset comprising:
a plurality of electrodes disposed on the headset and configured to provide stimulation to a predetermined region of the user's brain, and
a plurality of optical sensors, each optical sensor from the plurality of optical sensors positioned adjacent to an electrode from the plurality of electrodes and including a light emitter, a first light detector, and a second light detector, the first light detector configured to measure an intensity of light reflected from the user's brain and the second light detector configured to measure an intensity of light reflected from the user's scalp;

a controller communicatively coupled to the plurality of electrodes and the plurality of optical sensors, the controller configured to:
transmit stimulation instructions to at least one of the plurality of electrodes to cause the at least one of the plurality of electrodes to generate a transcranial stimulation to the user based on a stimulation parameter value,
receive a first signal indicative of the intensity of light reflected from the user's brain, and a second signal indicative of intensity of light reflected from the user's scalp,
determine a blood oxygenation level based on the first signal and a scalp oxygenation level based on the second signal, and
subtract the scalp oxygenation level from the blood oxygenation level to obtain an activity data associated with the predetermined region of the user's brain.
