Abstract:
Objective To establish the database of brain trigeminal evoked potentials for our laboratory,latency and interpeak latency of brain trigeminal evoked potentials were measured in normal volunteers.Methods Trigeminal nerves in 40 normal volunteers were stimulated with the evoked potential instrument.The results were collected with three-channel records in different ways at the same time.Results It showed two main waves,T1′(-) and T2′(+),in the brain trigeminal evoked potential records with C3,and their latencies were (3.020 5?0.828 9)ms and(6.736 0?1.393 9)ms;its T2-T1 interpeak latency was(3.743 8?1.206 0)ms.Conclusion C3 records showed more stability on brain trigeminal evoked potentials in normal volunteers,it would be helpful to investigate the brain trigeminal evoked potentials in patients.
