（Professor, Department of Bioengineering and Robotics, Graduate School of Engineering, Tohoku University） 「Recent Findings on Our Auditory System: It Is Highly Sensitive Owing to the Motility of Sensory Cells」 Even though the amplitude of tympanic membrane vibrations is only a few nanometers when we speak in a low voice, we can clearly understand what is being said. This is speculated to be due to cochlear amplification. The origin of this amplification is believed to be the motility of mammalian outer hair cells (OHCs), which are located in the organ of Corti of the cochlea. These are the main focuses of my talk. However, firstly, peripheral anatomy is overviewed. Then, the acoustic properties of the outer and middle ears are interpreted. An explanation of the cochlear function follows. Finally, the origin of the motility of OHCs, i.e., the motor protein |
