Brain Fingerprinting: A Review of the Behavioural Scientific Revolution

Brain fingerprinting is a novel neuroscientific technique that analyses brain responses to certain stimuli to find hidden information. Brain fingerprinting, which was invented by Dr. Lawrence Farwell in the early 1990s, has gained popularity in a variety of fields, including criminal justice, deception detection, and market research. The core principle of brain fingerprinting relies on the analysis of event-related potentials (ERPs) generated in response to specific stimuli, such as crime scene details or critical information relevant to an investigation. Researchers have refined ERP-based paradigms, incorporating advanced neuroimaging techniques like functional magnetic resonance imaging (fMRI) and electroencephalography (EEG), which have enhanced the accuracy and reliability of brain fingerprinting outcomes. This review paper offers a thorough analysis of brain fingerprinting, including information on its historical development, technique, guiding principles, how it works, methodology & it’s working procedure, potential advantages, disadvantages, range of applications, ethical issues of the non-invasive neuroscientific instrument. As evident, brain fingerprinting has evolved significantly, offering a promising avenue for forensic applications. As research continues to refine the technology and address ethical concerns, brain fingerprinting holds the potential to revolutionize criminal investigations and courtroom procedures, contributing to the pursuit of justice and truth.
