Qualitative Evaluation by ERP for Vibration Discrimination

摘要

We have developed a method of quantitative evaluation for vibration discrimination by event-related potentials (ERP). We made a modulation matrix of high-pass component f1: (40-200 Hz) and low-pass component f2: (2-20 Hz), and gave modulated vibrations to a forefinger by a piezoelectric vibrator. We examined ERP differences, which are amplitudes, areas and intervals, between a reference vibration of f1, f2) = (40, 2) Hz and controlled vibrations.
