1. A method of functional brain mapping of a subject comprising the steps of:

  • (a) illuminating an exposed cortex of a brain or portion thereof of the subject with incident light;

    (b) acquiring a reflectance spectrum of each picture element of at least a portion of the exposed cortex of the subject;

    (c) stimulating the brain of the subject;

    (d) during or after step (c) acquiring at least one additional reflectance spectrum of each picture element of at least the portion of the exposed cortex of the subject; and

    (e) generating an image highlighting differences among spectra of the exposed cortex acquired in steps (b) and (d), so as to highlight functional brain regions.
