The first and second lights have different skin penetration depths from each other depending on a wavelength.

A method is disclosed for generating a database to be used to set illumination of an adjustable light source. The method comprising: for a plurality of different users: identifying an individual user; setting a specific light profile of the adjustable light source, the specific light profile comprising information pertaining to a spectral content and/or intensity of light by which the individual user is exposed to; while exposing the individual user for the specific light profile, sensing data pertaining to a health condition and/or a behavior of the individual user; determining a data set linking the specific light profile, genomic data pertaining to the individual user, and the data pertaining to the health condition and/or the behavior of the individual user sensed while exposing the individual user to the specific light profile; and storing the linked data set in a database. A light control system is further provided.

Brain dysfunction can be treated by restructuring neural pathways in the brain. A desired area in the brain to form a new neural pathway is selected. The area receives a sequential combination of (1) transcranial photobiomodulation therapy (PBMT) including a series of pulses having a frequency matched to a target brain wave and (2) another transcranial stimulation (e.g., transcranial direct current electrical stimulation and/or transcranial magnetic stimulation). The different stimulation mechanisms ensure that neuroplasticity occurs to restructure a neural pathway that is dysfunctional in nature to a new neural pathway that conducts normally.

The invention relates to an optical stimulation device for stimulating nerve cells, wherein the stimulation device has at least one implant component, which is designed for implanting in a natural inner cavity of the body of a living being, through which cavity a bodily fluid flows, having the following features: a) the implant component has at least one supporting structure, which can be expanded in a radial direction for fastening in the natural inner cavity, b) a plurality of light sources is fastened to the supporting structure, which light sources are designed to emit light in the radial direction with respect to the supporting structure, c) a plurality or electrodes is fastened to the supporting structure, which electrodes are designed to capture electrical body signals, d) the supporting structure has a plurality of openings and/or channels, through which the bodily fluid can flow after implantation in the body. The invention further relates to a method for programming the parameter memory of a stimulation device.

The present disclosure relates to devices, methods and kits for accelerating the rate of whitening of teeth.

Systems and methods of the present disclosure are directed to systems and methods for treating cognitive dysfunction in a subject in need thereof. The system can include a light source and a speaker. A visual neural stimulation system provides, via the light source, visual stimulation having a first value of a first parameter. An auditory neural stimulation system provides, via the speaker, audio stimulation having a second value of the second parameter. A stimuli orchestration component selects, for a first time interval, one of the visual stimulation or the audio stimulation to vary based on a policy, selects, for the first time interval, the other of the visual stimulation or the audio stimulation to keep constant based on the policy, and provides causes the one of the visual neural stimulation system or the auditory neural stimulation system to vary the one of the visual stimulation or the audio stimulation.
