Based on wavelet transform to analyze rabbit somatosensory evoked potential.
Rabbits were narcotized and stimulated by 0.5Hz electric pulse. Potential of scalp was sampled at 3764Hz. Wave components of rabbit somatosensory evoked potential (SEP) can be located precisely through the method of continuous wavelet transform (CWT). Frequency feature of SEP can also be analyzed by CWT. The technique of continuous wavelet transform, which can project a one-dimension signal into a two-dimension time-frequency space, will become a useful method to process medical electronic signal. Key words: wavelet transform, somatosensory evoked potential, single-trial.
