  1. Corticofugal modulation of frequency tuning of inferior collicular neurons in big brown bat, eptesicus fuse us chinese science bulletin, 2000 in order to explore the possible mechanism of corticofugal modulation of excitatory frequency tuning curves ( eftcs ) of midbrain neurons, we examine the change of sharpness, frequency - intensity response area, minimum threshold of both eftcs and inhibitory frequency tuning curves ( iftcs ) of inferior coliicular neurons during corticofugal modulation using two - tone inhibition paradigm and micro - electrical stimulation technique

    第二章大棕幅聽皮層對中腦下丘聽神經元頻率調諧曲線的調制科學通報, 2000用雙聲刺激的方法和電刺激技術,進一步研究了在激活聽皮層前後下丘聽神經元興奮性和抑制性頻率調諧曲線的銳度、頻率強度反應區域、最低閾值的協同變化
  2. The aim of this study is to investigate theoretically the possibility for activation of small mammalian myelinated nerve fibers without activating larger ones when stimulating a nerve fiber bundle with a monopolar point electrode using biphasic pulses, which can reduce the electrochemical damage resulted from stimulation pulses to nerve fibers. a simulation system for studying the electrical properties of mammalian myelinated nerve fibers was built based on a simple infinite and homogeneous volume conductor model. by use of an asymmetric but charge - balanced stimulation waveform, the sensitivity of excitation and blocking threshold of nerve fibers to fiber diameter, electrode - fiber distance was calculated. the results show that selective activation of small mammalian myelinated fibers may be possible in a region at some distance from the electrode using biphasic pulses

    本研究的目的是要從理論上探討利用單電極雙向脈沖刺激實現哺乳動物神經纖維選擇性刺激, (即當刺激一束神經時,不興奮粗神經而興奮細神經)的可能性.雙向脈沖刺激可以降低刺激脈沖對神經纖維產生的電化學損傷.為研究哺乳動物有髓神經纖維的電特性,建立了一個基於簡單的無窮大、各向同性的容積導體模型的模擬系統.利用該模擬系統,採用「不對稱但電荷平衡」的雙向脈沖刺激,計算了神經纖維的興奮和阻斷閾值與纖維直徑、纖維-電極間距離的關系.結果表明:在距電極一定距離內採用該雙向脈沖刺激模式確實可以實現哺乳動物有髓神經纖維的選擇性興奮
