Transcranial examination of the brain

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 corresponding to blood volume.
