Lagenar potentials of the vocal plainfin midshipman fish, Porichthys notatus.

摘要: The plainfin midshipman fish (Porichthys notatus) is a species of marine teleost that produces acoustic signals are important for mediating social behavior. auditory sensitivity the saccule well established in this species, but and function midshipman’s putative lagena unknown. Here, we characterize auditory-evoked potentials from hair cells reproductive type I males to determine frequency response behaviorally relevant stimuli. Lagenar were recorded caudal medial region lagena, while stimuli presented by an underwater speaker. Our results indicate has similar low-frequency based on sound pressure acceleration (re: 1 µPa ms−2, respectively), thresholds higher across all frequencies tested. relatively high may be encoding levels when close source.
