Abstract:
A cognition spectrophotometer system for transcranial brain examination using electromagnetic radiation of a visible or infrared wavelength, comprising:an optical unit constructed to be worn by a user, said unit including a light source adapted to introduce transcranially from an input port, placed at a input location on the exterior of the head, electromagnetic radiation of said wavelength into the brain; and a light detector adapted to detect, at a detection port placed at a detection location on the exterior of the head, radiation that has migrated in the brain; a stimulation module constructed and arranged to cause stimulation of a brain activity while introducing said radiation at said input port; a remote communication unit including a transmitter and a receiver; and a processor adapted to process signals of said detected radiation that has migrated in the brain to create processed data and determine a characteristic of said brain activity by correlating said processed data to said caused stimulation of said brain activity, wherein said processor is constructed to provide said processed data reflecting a difference between stimulated and non-stimulated tissue.
