Brain Fingerprinting

The accused in Hathras rape case will undergo brain fingerprinting.

Key takeaways

Brain Electrical Oscillation Signature Profiling (BEOSP) is also known as brain fingerprinting.
It is a neuropsychological method of interrogation in which the accused’s participation in the crime is investigated by studying their brain’s response.
The BEOSP test is carried out via a process known as an electroencephalogram, conducted to study the electrical behaviour of the human brain.
Under this test, the consent of the accused is first taken and they are then made to wear caps with dozens of electrodes attached to them.
The accused are then shown visuals or played audio clips related to the crime to check if there is any triggering of neurons in their brains which then generate brainwaves.

The test results are then studied to determine the participation of the accused in a crime.
