| Résumé : | The effects of 14 filter conditions with cutoff ranging from 3 kc/sec to 50 c/sec and with either 6 or 24 dB/octave roll off were studied when averaging the somatosensory cerebral potentials evoked by electrical stimulation of fingers in normal adult men. Severe distortions of latencies and voltages were observed for low pass filtering below 1 kc/sec. It is emphasized that the overall system bandpass should extend to 3 kc/sec when studying the early components and when estimating the onset latency of the surface negative N1 component. Precise information about the system bandpass used should be included in published reports. © 1974. |
