AN AUTOMATIC SYSTEM FOR MEASUREMENT OF THE LATENCY IN POTENTIALS EVOKED BY TACTILE STIMULI
M. De Luca, S. Rapuano
Abstract:
The paper faces the problem of recording and analyzing the sensory potentials evoked by tactile stimuli in a non-invasive way. These signals present a very low SNR. Therefore, at now, this very selective investigation technique requires harmful needle electrodes to acquire them. The paper proposes both a new recording method based on surface electrodes and a signal processing technique. This technique greatly improves the SNR of the signals. The new method has been validated measuring the latency on simulated as well as actual signals. The results of the validation phase are presented and discussed.
