We measure brain activity, not anxiety. The fairer lie detector test for Marsh Lane.
Choose the lie detector test that science backs. In Marsh Lane, our P300 EEG protocol is based on decades of peer-reviewed research. It is objective, non-invasive, and consistently outperforms the polygraph in detecting concealed information.
Instead of relying on sweating, blood pressure or breathing like a polygraph, P300 EEG testing looks directly at how the brain reacts to information it recognises.
When you see or hear something meaningful, your brain produces a characteristic “P300” wave. During the test we mix neutral and relevant details while our EEG system tracks this response in real time.
If someone in Marsh Lane claims not to know certain facts but their brain reacts strongly to those exact details, that can indicate concealed knowledge or deception. This provides a more objective basis for assessing truthfulness.
Sensors sit gently on the scalp – there are no needles or pain. The person being tested simply sits comfortably while we run a carefully structured set of sequences and record the data.
We provide P300 response based lie detector test for individuals, couples, families, employers and legal professionals across Marsh Lane.

Monitors sweating, blood pressure and breathing – all of which can be influenced by nerves, fear or simple counter‑measures. This is why many clients now prefer a modern lie detector service based on brain responses.

Our Marsh Lane lie detector service is built on established neuroscience, not guesswork. The P300 response has been studied for decades in laboratories and forensic settings.
The P300 is a measurable brainwave that appears around 300 milliseconds after a person recognises meaningful information. During testing, we show or read a mixture of neutral and case‑relevant items while the EEG headset measures these responses.
Unlike changes in heart rate or sweating, the P300 response is generated in the cortex – the memory and decision‑making areas of the brain. It is extremely difficult to consciously suppress or fake this response, which is why research shows up to 95% accuracy.
Our protocols are based on peer‑reviewed “guilty knowledge” and “concealed information” test designs used internationally. We are transparent about limitations and always advise Marsh Lane clients to see results as strong evidence, not an automatic court verdict.
