... auditory pathways, showing threshold increases of up to 30 dB re. 1 μPa. Here, we investigated the impact of the acoustic environment on sensitivity at the sensory receptor level of the inner ear saccule, which is considered to serve mainly a hearing function in most teleosts ( Popper and Fay, 1973 , 1993...

... to detect and locate ‘singing’ males that produce multiharmonic advertisement calls in the shallow-water, intertidal breeding environments. Previous work showed that females possess sexually dimorphic, horn-like rostral swim bladder extensions that extend toward the primary auditory end organs, the saccule...

...Sheryl Coombs; Richard R. Fay; Andreas Elepfandt SUMMARY In goldfish and other otophysans, the Weberian ossicles mechanically link the saccule of the inner ear to the anterior swimbladder chamber (ASB). These structures are correlated with enhanced sound-pressure sensitivity and greater sensitivity...

...Zhongmin Lu; Zemin Xu; William J. Buchser SUMMARY The saccule is known to play an important role in hearing in fishes. In this study we investigated spatial frequency selectivity of single saccular afferents in a teleost fish (the sleeper goby, Dormitator latifrons ) to acoustic particle motion...

..., goldfish hearing recovered significantly (mean TTS<4 dB). Increased apoptotic activity was observed in the saccules and lagenae between 0 and 2 days post-exposure. Immediately after noise exposure, the central and caudal regions of saccules exhibited significant loss of hair bundles. Hair bundle density...

... in the pre-adult stages are unknown. Midshipman fish, like other teleosts, use the saccule as the main acoustic end organ of the inner ear. In this study, we examined the discharge properties and the frequency response dynamics of auditory saccular afferent neurons in pre-adult midshipman (∼4–12 months...
