An auditory stimulus (vibration of air in physical terms) is encoded into excitatory neural activities in the cochlea, transmitted through the auditory pathway and finally fed into the auditory cortex. In addition, ihibitory neural networks seem to play an important role in sharpening the frequency tuning. Here in the present talk, I would like to show the results of recent researches investigating the effects of auditory attention on the population-level frequency tuning and the potential clinical use of lateral inhibitory interactions on tinnitus patients.

聴覚刺激（物理的には空気振動）は蝸牛で興奮性の神経活動に変換され聴覚経路を経て聴覚野に収束する。さらに抑制系の神経ネットワークが周波数調律の向上に寄与していると考えられる。このセミナーではAttentionが周波数調律に及ぼす影響と抑制系の神経ネットワークを利用した耳鳴患者の治療法に関して発表する。
