Abstract:
OBJECTIVE:To investigate the characteristics of OERPs of young adults.
METHOD:Subjects included 55 young volunteers (male/female 25/30) with normosmic. A complete ENT examination, A subjective olfactometry with T&T olfactometer were performed in all subjects. OERPs with stimulus isoamyl acetate (<1,648 x 10(-6)), and air control were obtained in volunteers.
RESULT:OERPs were obtained in both male and female volunteers. P2, the primary component of OERPs, was identified in all volunteers. No significant difference was found in latencies of the components of OERPs between male and female volunteers. N1-P2 interpeak amplitudes were larger in the female subjects than male subjects (P<0.05).
CONCLUSION:P2 component of OERPs is identified in all young adults, both gender and interstimulus interval have impact on N1-P2 interpeak amplitudes.
