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22 paired inferior collicular neurons were obtained in the experiment. the neurons were recorded in the depth of 198 - 1254 u m ( 544. 59 ? 72. 37 n m, m + sd ), and their bfs were 11. 25 - 59. 29 khz ( 26. 77 + 9. 95 khz, m ? d ) : the minimum thresholds ( mts ) werelo - 66 db spl ( 38. 14 ? 14. 39 khz, m + sd ) ; the latencies were 4. 0 - 16. 0 ms ( 8. 19 + 3. 14 ms, m + sd ) ; the best intervals between paired sound pulses were 0. 01 - 28. 71 ms ( 3. 93 + 2. 52 ms, m ? d ) 0 the results showed : l ) there were interactions between the neurons in the iso - frequency lamina and hetero - frequency lamina which included mutual inhibition ( 18 / 22, 81. 8 % ) and mutual facilitation ( 4 / 22, 18. 2 % ), and the mutual inhibition in iso - frequency lamina was stronger than that in hetero - frequency lamina ; 2 ) the mutual inhibition decreased with sound level increasing ( p < 0. 001, anova ) ; 3 ) the analysis of the inhibition of discharge rate at lodb above mt showed that the inhibition increased when the paired neurons " bfs difference decreased ( r = - 0. 545, p = 0. 0006 ) ; 4 ) the mutual inhibition of paired neurons can sharpen the frequency tuning and the effect increased when the frequency was away from the bf ; 5 ) the changes in q10, q30 decreased with bfs difference of the paired neurons increasing ; 6 ) the mutual facilitation between paired neurons not only increased discharge rate, but also widened the frequency tuning, i. e., increased response frequency
結果表明： 1 ）同頻層神經元之間或者非同頻層之間神經元之間存在相互作用，這種作用既有相互抑制（ 18對，佔81 . 8 ） ，也有相互易化（ 4對，佔18 . 2 ） ，且同頻層神經元之間的相互抑制作用較非同頻層神經元之間的相互抑制作用要強； 2 ）神經元對低刺激強度反應時，所受到的相互抑制作用較強，隨著聲刺激強度加大，抑制作用逐步降低（ p 0 . 001 ， anova ） ； 3 ）對閾上10db放電率抑制百分比進行的分析顯示，配對神經元之間的最佳頻率差越小，相互抑制作用越強（ r = - 0 . 545 ， p = 0 . 0006 ） ； 4 ）配對神經元之間通過相互抑制作用可表kx碩士學位論文waiaster 』 sthesis現出調諧銳化作用，該作用的效率與頻率有關， bf處的銳化作用較低，偏離bf時其銳化作用逐步加強； 5 ）頻率銳化作用的效率與bf差有關，隨著配對神經元之間的bf差擴亢q10 ， q30值的變化逐漸減小，其變化百分比與配對神經元之間的頻率差存在明顯相關； 6 ）配對神經元之間的相互易化作用不僅表現在放電率增加上，也表現在頻率調諧曲線的擴寬，即頻率響應范圍擴大。As a committed it practitioner in china for a decade, we have made significant investments to incubate a team of elite local it professionals, develop customized software products and establish a nationwide servicing network in the country. with the fast shifting economic and social landscape of the country, we believe that this is the right time for us to move one strategic step forward, to get in pulse with the needs of the chinese people and assimilate our offerings into their everyday life.
