This study investigates somatosensory evoked potential (SEP) patterns in the C3 somatosensory area with varying frequency and intensity of vibrotactile stimuli. The study subjects included 13 men ($23.2\pm 0.8$ years) and seven women ($22.3\pm 1.5$ years) who were right-handed and had normal cognitive function. The participants were subjected to three intensity levels (0.25, 0.38 and 1.3$$g) and eight frequencies (10, 50, 100, 150, 200, 225, 250 and 300$$Hz) of vibrotactile stimuli on the distal phalanx of their right index finger. The peak values of SEP patterns generated in response to high-frequency vibrotactile stimuli were greater than those generated because of low-frequency flutter. Moreover, the peak values increased as the stimulus intensity increased from 1$$g to 3$$g. In these results, the maximum and minimum peak, and peak to peak values of SEP pattern in the C3 somatosensory area increased with an increase in the stimulation intensity and frequency of the vibrotactile stimuli. Data on the SEP patterns generated in response to various frequencies and intensities of somatosensory stimuli and the development of relevant databases will elucidate the various clinical applications and applicable domains where SEP assessment can be beneficial.

这项研究调查了C3体感区域中的体感诱发电位（SEP）模式，该频率随触觉刺激频率和强度的变化而变化。研究对象包括13名男性（$23。2\pm 0。8$ 年）和七名妇女（$22。3\pm \mathrm{1个}。5$年（右手）并且具有正常的认知功能。参与者经历了三个强度级别（0.25、0.38和1.3）$$g）和八个频率（10、50、100、150、200、225、250和300$$右食指远端指骨上的触觉刺激（Hz）。响应于高频触觉刺激而产生的SEP模式的峰值大于由于低频颤动而产生的SEP模式的峰值。此外，随着刺激强度从1增加，峰值也增加$$克至3$$G。在这些结果中，随着触觉刺激强度和频率的增加，C3体感区域中SEP模式的最大和最小峰以及峰到峰值增加。响应于各种频率和强度的体感刺激而产生的SEP模式数据以及相关数据库的开发将阐明SEP评估可能有益的各种临床应用和适用领域。
