Examination and imaging of brain cognitive functions
First Claim
1. A method for examining a brain function of a subject, comprising the acts of:
- introducing optical radiation in the visible to infra-red range from a light source into the brain of a subject and detecting radiation that has migrated in a brain region to a detector;
providing brain stimulation while introducing and detecting said optical radiation;
storing said detected radiation and creating optical data; and
evaluating said optical data to determine a brain function of the subject.

Abstract
A system and method for examining or imaging brain functions of a subject includes a light source and a light detector located on the exterior surface of the subject'"'"'s head. The light source introduces transcranially optical radiation into the brain of a subject, and the light detector detects radiation that has migrated in a brain region from the light source to the detector. The system also provides brain stimulation and evaluates the detected radiation to determine a brain cognitive function of the subject. One embodiment of the system can detect a brain disorder. Another embodiment of the system can detect “deceit.” In addition to the optical module, the system may include other optional modules such as an EEG module, an MEG module, a thermography module, a respiratory module, a skin conductivity module, and a blood pressure module.

20. A method for detecting deceit by a subject, comprising the acts of:
-
introducing optical radiation in the visible to infra-red range from a light source into the brain of a subject and detecting radiation that has migrated in a brain region to a detector;
providing brain stimulation and receiving a response from said subject while introducing and detecting said optical radiation;
storing said detected radiation and creating optical data; and
evaluating said optical data to determine whether said response was a knowingly false response. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
