What Is a P300 Lie Detector Test?

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.

Brain Recognition Response

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.

Why It Works for Lie Detection

If someone in London 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.

Non‑Invasive & Comfortable

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.
