Sex differences in vocalization are reflected by event-related potential components in the music frog.

摘要: Sex differences in vocalization have been commonly found vocal animals. It remains unclear, however, how animals perceive and discriminate these differences. The amplitudes latencies of event-related potentials (ERP) components can reflect the auditory processing efficiency time course. We investigated neural mechanisms Emei music frog (Nidirana daunchina) using an Oddball paradigm with ERP. recorded analyzed eletroencephalogram (EEG) signals from forebrain midbrain when subjects listened to white noise (WN) conspecific sex-specific vocalizations. that (1) both some ERP evoked by calls were significantly higher than those WN, suggesting frogs vocalizations background noise; (2) most female or longer male calls, implying sex vocalization; (3) there significant between subjects, a sexual dimorphism perception. Together, present results indicate could noise, male's female's ones, perception existed this species.
