Brain Electrical Oscillation Signature Profiling (BEOSP)

Brain Electrical Oscillation Signature Profiling (BEOSP), also called the ‘Brain Fingerprinting’ or “Brain mapping”, is an Electroencephalogram (EEG) technique.

Key Points

  • Electroencephalogram (EEG) is a test that is used to detect abnormalities in brain waves.
  • The test does not have any effect on the health of the person undergoing it.
  • BEOSP is a neuro-psychological method, usually deployed in interrogating a suspect’s participation in a crime.
  • This technology works on the difference between the response of the brain on a piece of information of an event, when the person has taken part in an incident, and when he has received the same information from secondary sources.
  • No questions are asked to the person undergoing the BEOSP test instead they are subjected to some events, scenarios and the result is analyzed on the basis of brain activity. Two types of probes are used to stimulate the brain of the person undergoing the test- audio and visual probes.
  • It helps in reaching the truth in criminal cases; however, the consent of the accused is necessary to conduct the BEOSP test.
  • BEOSP was developed by a neuroscientist, Champadi Raman Mukunandan. He was also a former professor and clinical psychology head at the National Institute of Mental Health and Neurosciences, Bangalore India.

Hathras Case Accused undergo BEOSP Test

The four accused in the alleged rape and murder of the women in Hathras, Uttar Pradesh, have undergone the Brain Electrical Oscillation Signature Profiling (BEOSP) test.

Similar Tests

Polygraph is another test conducted for the interrogation of criminals. It is commonly known as the “Lie-Detector Test”. In this test, a device is connected to the person that measures different indicators like pulse, blood pressure, respiration, and skin conductivity while he is answering the questions.  However, it is also believed that the test is not very effective.
