Patent ID: 8574279

Claim:
A method for enhancing positive outlook of a person with hemispheric asymmetry comprising identifying a person with a deficient positive outlook in need of enhancement; measuring a left hemispheric emotional valence for a left hemisphere of a brain of the person and a right hemispheric emotional valence for a right hemisphere of the brain of the person to identify hemispheric asymmetry; determining which hemisphere of the brain of the person with hemispheric asymmetry has a more positive valence, and which hemisphere of the brain has a more negative valence; and transcranially applying light energy having a wavelength of between 300 nm to 1500 nm and a power density at the scalp of up to 320 mW/cm 2 to the brain of said person with the deficient positive outlook with hemispheric asymmetry, wherein the light energy is transcranially applied to the lateral forehead to activate the underlying cortex of the brain hemisphere with a more positive valence for a period of at least four minutes, such that the positive outlook of the person is enhanced.
