P300 EEG vs Traditional Methods

P300 EEG Brain Wave Technology

P300 EEG Technology

95% Accuracy Rate

Direct measurement of brain activity in response to relevant stimuli. Superior scientific foundation and robust against countermeasures.

  • ✓ Measures brain activity directly
  • ✓ Stronger legal standing in UK courts
  • ✓ Faster testing (15–20 minutes)
  • ✓ Resistant to manipulation
  • ✓ Expert witness testimony included
Traditional Methods Comparison

Traditional Methods (Comparison)

65–75% Accuracy

Traditional physiological response measurement (heart rate, blood pressure, skin conductance). More vulnerable to countermeasures and external factors.

  • • Can be influenced by countermeasures
  • • Longer sessions (2–3 hours)
  • • Limited accuracy compared to P300

    P300 EEG Technology & Accuracy

    P300 EEG measures direct neural recognition through event-related potentials, while traditional methods measure indirect physiological changes. This provides superior accuracy and resistance to countermeasures.

    • P300 EEG: 95% accuracy, measures brain activity directly
    • Traditional Methods: 65–75% accuracy, measures physiological responses
    • Testing Time: P300 EEG 45-90 minutes vs traditional 2-3 hours
    • Manipulation Resistance: P300 EEG cannot be manipulated

    P300 EEG consistently delivers 95% accuracy through validated neurological protocols. Accuracy benefits from:

    • Validated event-related potential (ERP) protocols
    • Multiple-trial averaging and artifact rejection
    • Direct brain activity measurement
    • Certified examiners and quality control checks
    • Court-admissible scientific methodology

    P300 EEG measures involuntary neural recognition responses that occur within milliseconds. The technology is designed to detect and prevent manipulation attempts through sophisticated control mechanisms.

    Test Process & Preparation

    • P300 EEG Testing: 15–20 minutes (setup, calibration, testing, results)
    • Complex Cases: May require additional time for comprehensive analysis
    • Consultation: Pre-test consultation included in all packages
    • Get 7–8 hours sleep the night before
