    Abstract
    Research has shown that photo-biomodulation of neurons with near-infrared (NIR) light can stimulate their regeneration, and thus various research groups have developed devices that emit NIR light transcranially (through the skull) to stimulate neural growth in the brain in an effort to treat neurological diseases such as Multiple Sclerosis (MS) and Alzheimer’s. However, it is not clear that clinical device designs illuminate cells in the brain with similar parameters as those shown effective for neuro-regeneration in pre-clinical work. This project employed computational modeling and simulations to assess the effect of device design parameters on transcranial light propagation, in order to optimize illumination of brain tissue and cells and thus ultimately improve clinical results of transcranial NIR-emitting devices for neuro-regeneration. Specifically, this project consisted of the development of two computational models for transcranial NIR-emitting devices and the evaluation of three device parameters: wavelength, photon number, and power density, on transcranial NIR light propagation.

    Export search results

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
