Methods and systems for providing stimuli to the brain

An apparatus to provide stimulation to a user, the apparatus comprising:

• a frame configured to be worn on a head of the user;
• a controller programmed to generate a plurality of inputs including a left light source input, a right light source input, a left auditory source input, and a right auditory source input;
• a left light source configured to generate a left visual stimulus pattern from said left light source input;
• a right light source configured to generate a right visual stimulus pattern from said right light source input;
• a left auditory source configured to generate a left auditory stimulus pattern from said left auditory source input;
• and
• a right auditory source configured to generate a right auditory stimulus pattern from said right auditory source input;
• wherein said controller is programmed to generate inputs which alternate between a first input including simultaneously generating the left light source input and the right auditory source input, and
• a second input including simultaneously generating the right light source input and the left auditory source input,
• wherein one or more of the left visual stimulus pattern or the right visual stimulus pattern comprises a sequence of stimulus patterns including a first stimulus pattern having a first frequency component between 3.75 Hz and 4.25 Hz, a second stimulus pattern having a second frequency component between 1.25 Hz and 1.75 Hz, and a third stimulus pattern having a third frequency component between 0.25 Hz and 0.75 Hz.

A method of treating a neurological disease or condition or providing performance enhancement, the method comprising:

• administering a therapeutically effective amount of a sensory stimulus to a user, wherein said sensory stimulus includes alternating the sensory stimulus between:
• a first sensory stimulation including simultaneously providing a left visual stimulus pattern to a left eye of the user and a right auditory stimulus pattern to a right side of a head of the user;
• and
• a second sensory stimulation including simultaneously providing a right visual stimulus pattern to a right eye of the user and a left auditory stimulus pattern to a left side of the head of the user,
• wherein one or more of the left visual stimulus pattern or the right visual stimulus pattern comprises a sequence of stimulus patterns including a first stimulus pattern having a first frequency component between 3.75 Hz and 4.25 Hz, a second stimulus pattern having a second frequency component between 1.25 Hz and 1.75 Hz, and a third stimulus pattern having a third frequency component between 0.25 Hz and 0.75 Hz.

A method of managing pain, said method comprising:

• administering a therapeutically effective amount of a sensory stimulus to a user, wherein said sensory stimulus includes alternating the sensory stimulus between:
• a first sensory stimulation including simultaneously providing a left visual stimulus pattern to a left eye of the user and a right auditory stimulus pattern to a right side of a head of the user;
• and
• a second sensory stimulation including simultaneously providing a right visual stimulus pattern to a right eye of the user and a left auditory stimulus pattern to a left side of the head of the user,
• wherein at least one selected from the group consisting of the left visual stimulus pattern, the right visual stimulus pattern, the left auditory stimulus pattern, and the right auditory stimulus pattern comprises a sequence of stimulus patterns including a first stimulus pattern having a first frequency component between 3.75 Hz and 4.25 Hz, a second stimulus pattern having a second frequency component between 1.25 Hz and 1.75 Hz, and a third stimulus pattern having a third frequency component between 0.25 Hz and 0.75 Hz.
