Method and apparatus for wearable device with EEG and biometric sensors
Devices and methods for monitoring, stimulating, and entraining electrical activity generated by the brain of a person are provided. Electroencephalography (EEG) and photobiomodulation (PBM) devices in the form of headphones for monitoring, stimulating, and entraining electrical activity generated by a person's brain are described, along with methods for monitoring and stimulating a person's cognitive and physiological state using the provided devices. PBM light is pulsed to stimulate an increase in targeted brainwave frequencies through entrainment and providing additional energy to mitochondria. PBM stimulation is combined with EEG sensors and neurofeedback. The neurofeedback may be used to assist users with stress, anxiety, fatigue, mood, creativity and mental focus and acuity.
