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.
