Abstract

A cognition spectrophotometer system for transcranial brain examination using electromagnetic radiation of a visible or infrared wavelength includes an optical unit, a stimulation module, a remote communication unit, and a processor. The optical unit includes 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 the 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. The stimulation module is constructed and arranged to cause stimulation of a brain activity while introducing the radiation at the input port. The remote communication unit includes a transmitter and a receiver. The processor adapted to process signals of the detected radiation that has migrated in the brain to create processed data and determine a characteristic of the brain activity by correlating the processed data to the caused stimulation of the brain activity, wherein the processor is constructed to provide the processed data reflecting a difference between stimulated and non-stimulated tissue.
