response latency
4.Results : According to the differences in latency after giving the electrical stimuli, we can get the M20, M35 and M60 somatosensory evoked fields from the primary somatosensory cortex. We only analyzed the gender difference of M20 response in latency, amplitudes and location because M35 and M60 were apt to affect by interstimulus interval.
6.Methods The response thresholds of MASSR and the behavioral thresholds were recorded from 28 normal hearing adults(56ears) at 0.5,1,2,and 4kHz. The response thresholds of Tp-ABR、 the latency and the interpeak lantency of wave Ⅰ、 Ⅲ、Ⅳ and the behavioral thresholds of Tp-ABR, were recorded from 28 normal hearing adults(56ears) at 0.5,1,2, and 4kHz.
