“B.E.O.S.” refers to a signature extracted from the electrical oscillations of the brain of a person, obtained while presenting probes related to specific events in which the person is suspected to have participated. The signature represents the presence of electrical activation pattern indicating retrieval of Experiential Knowledge of the said participation. The signature is absent while the subject retrieves information, which one could have conceptually (from sources other than participation) acquired.
B.E.O.S is also called Brain-Mapping in some parts of the world which is a misnomer.
Neural processing / activation are different during retrieval of knowledge acquired through experience in comparison with retrieval of knowledge acquired through conceptual learning. Retrieval of Experiencing Knowledge may have components of sensory-motor mental imageries representing reality contacts and verifications, though the knowledge derived is only subjectively verified and interpreted.
Extensive research in Neuroscience has shown that the brain activation pattern is significantly different during ‘remembering’ and ‘knowing’. Remembrance is always that of past personal episodes which constitutes the experiences of the individual. On the other hand knowing represents retrieval from the knowledge bank of the brain used for recognition of the entities of world and their conceptualizations.
The technique has immense forensic and medical application as it can extract ‘signature’ related to specific experiences with personal significance, one has gone through in the past and hence one is bound to remember. These experiences may be related to personal participation in activities, which may include planning, discussions, and even strong intentions which served as motives for execution of specific actions. Generally one remembers only those experiences which have personal significance to the self. Emotions, gains, and such personal values attached to the participation render an event personally significant and retrievable.
An important feature of the test is that the subject is not presented with questions and need not answer or provide any response while listening to the probes.
“Neuro Signature System” represents the equipment designed and developed by Axxonet. It records scalp electrical activity from a person using multiple electrodes and the N.S.S. program extracts the signature, if present, when the subject silently listens to the probes. The probes are presented in auditory mode.
The Neuro Signature System carries out extensive analyses of the electrical oscillations for computing both frequency and time domain related changes induced and provoked by the probes. At the end of the automated analyses, the system prints out an interpreted report which tells the nature of involvement, if any, of the subject in the said activities probed by the test. Based on the probes presented, it can indicate if the subject took part in an activity, the specific role played by one, whether related to planning or execution. It can also help identify a person from a group who has performed a specific activity or determine the differential roles of the individuals tested.
Continuous research is in progress at Axxonet for better understanding and refining analysis methods for the detection of the various changes recorded during the presentation of the probes, their display, and their neurocognitive significances.
N.S.S. BEOS carries out the entire range of analyses and the interpretation of the analysed results automatically and prepares the Forensic Report of the suspect.
The test can be used as a powerful investigatory aid. The investigating agency has the duty to be confidential about the outcome revelations of the test, unless the same is otherwise revealed by material evidence and are presented in a court of law.
