The Centre for Forensic Neuroscience, established in 2002, provides polygraph testing services (often referred to as lie detection) and credibility assessment with the UK’s largest team of dedicated expert examiners, with Dr Keith Ashcroft as the Principal Forensic Polygraph Examiner.

Another specialised polygraph technique allows the investigator to determine if a crime suspect recognizes crime relevant information. The Concealed Information Test (CIT), or sometimes referred to as the Guilty Knowledge Test, uses a set of multiple-choice questions which refer to crime-specific details of the investigation in hand.

We are also partners with No Lie MRI, Inc. which provides unbiased methods for the detection of deception and other information stored in the brain. Specifically, Magnetic resonance imaging (MRI) uses a magnetic field to provide detailed pictures of our internal anatomy. Functional magnetic resonance imaging (fMRI) uses an MRI to show localized brain activity.
