Embodiment 1

[0027] See attached figure 1 , a kind of brain neurotransmitter-based polygraph method described in this embodiment, when the tester asks various questions and the subject answers the questions, the signal of the acupoints on the subject's head is measured by a dual optical path sensor , After the data is processed by the acquisition control system and input into the computer, it can be judged whether it is true or false.

[0028] See attached figure 2 , in this embodiment, the acupoints for signal acquisition of the subject are 4 acupoints in the left and right frontal regions and left and right temporal regions on both sides of the subject's brain region, using the 4-way red and infrared double beam reflection method The data signals corresponding to the 8-way relative brain oxyhemoglobin concentration changes corresponding to the above acupoints were respectively measured. The wavelength of infrared light is 850nm, two light-emitting diodes are used as the light source, ...

Abstract

A lie detecting method used for public security department includes such steps as giving different questions to the person to be detected, answering the questions by the person while using the reflecting method of two red light beams and two infrared light beams to respectively obtain the 8 data signals about the concentration variations of cerebral oxyhemoglobin on 4 acupoints in left and right frontal and temporal regions of the person, inputting them to computer, processing said data signals by calculation, configuring the recognizing parameters based on the characteristic energy value of cerebral nerve mediator, and judging if the person tells a lie according to a critical reference value.

Description

technical field [0001] The invention relates to a method for detecting and diagnosing whether a subject is lying when a public security department handles a case, in particular to a method for detecting lies based on brain neurotransmitters. Background technique [0002] Throughout the century-old history of polygraph science, the focus of research is how to improve the accuracy of polygraph detection. The method of lie detection has changed from emotional experimental psychology to cognitive experimental psychology, and the corresponding processing information has evolved from physiological signals to functional brain regions, and then it will definitely target biochemical information such as brain neurotransmitters. [0003] Compared with the accuracy of lie detection technology, the traditional ones based on physiological indicators (such as skin resistance and heart rate) are 85%; those based on physical indicators (such as brain region position...
