Neural and Behavioral Mechanisms of Audition
9 NEURAL AND BEHAVIORAL MECHANISMS OF AUDITION ANDREW H. BASS ZHONGMIN LU
1. Introduction 2. Behavioral Studies of Audition 3. Peripheral and Central Auditory Pathways 3.1. Auditory System 3.2. Vocal Motor Inputs to Auditory System 4. Neurophysiological Mechanisms of Audition 4.1. Encoding of Vocal Signals 4.2. Directional Hearing 5. Auditory Lateral Line Integration 6. Vocal Modulation of Inner Ear and Lateral Line 7. Steroid Hormones and Seasonal Changes in Hearing 8. Future Directions
1. INTRODUCTION The auditory system of fish, like that of other vertebrates, is adapted to the detection of sound, a mechanical disturbance that leads to the vibration of molecules in any medium. The past decade has witnessed major advances in our understanding of the behavioral and neural mechanisms of audition among teleost fish, the largest group of living fishes. Since there are several reviews of auditory mechanisms among teleosts (Bass and Ladich, in press; Bass and McKibben, 2003; Ladich and Bass, 2003a,b; Lu, 2004; Bass et al., 2005), we will highlight the major points of those summaries, while providing more complete coverage of the recent findings in this field of study. The focus will be on two main topics, mechanisms of vocal/acoustic communication among sound producing/sonic fish and mechanisms of directional hearing among sonic and nonsonic species.
