1. A non-invasive detection system, comprising:

  • an optical source configured for delivering sample light into a head, such that a portion of the sample light passes through a target voxel comprising brain matter in the head and is scattered by the head as signal light, wherein the wavelength of the sample light is in the range of 950-1080 nanometers, such that the signal light is encoded with a time-varying optical absorption of the target voxel;

    at least one detector configured for detecting the signal light; and

    a processor configured for determining changes in the level of water concentration or relative water concentration of the target voxel based on the time-varying optical absorption of the target voxel encoded within the detected signal light, and determining whether or not neural activity exists within the target voxel based on the determined changes level of the water concentration or relative water concentration of the target voxel.
