What is Brain Fingerprinting? Brain Fingerprinting is a scientific  technique to determine whether or not  specific information is stored in an  individual's brain.

Quick Overview Invented By Dr Lawrence A. Farwell. It s a patented technique of proven accuracy  in US government tests. Ruled Admissible in one US Court   as scientific  evidence. • It has a record of 100% Accuracy.

How it works ?   On seeing a previously known information, a  specific measurable brain response known as a  P300  or  MERMER   i.e.   M emory and Encoding Related Multifaceted Electroencephalographic Response is elicited by the brain of a subject.

What is P300/  MERMER ? A MERMER is a part of the brainwave  observed in response to familiar information. When the brain recognizes something,  neurons are fired synchronously, eliciting  characteristic changes in brain activity.  It is these changes, that investigators look for  when trying to determine whether someone  recognizes a particular piece of information.

Continued… When a person is exposed to a rare, but  meaningful information, there is increase in  neuron activity which results in an increase in  voltage, typically within 300 1000msec after  the stimulus, and that response with increases  voltage is known as P300.  The utility of the P300 in detection of  deception was recognized as early as 1988,  However, the P300 has only a 87.5% success  rate in revealing the presence of relevant  information in one s brain.

Continued. .. But Farwell’s test is based on the discovery that the P300 is only a subcomponent of a more complicated response called a MERMER. The MERMER, includes the P300 and another longer latency, electrically negative subcomponent with a latency of up to two seconds post-stimulus
