| 1. | 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
结果表明： 1 )同频层神经元之间或者非同频层之间神经元之间存在相互作用，这种作用既有相互抑制( 18对，占81 . 8 ) ，也有相互易化( 4对，占18 . 2 ) ，且同频层神经元之间的相互抑制作用较非同频层神经元之间的相互抑制作用要强； 2 )神经元对低刺激强度反应时，所受到的相互抑制作用较强，随着声刺激强度加大，抑制作用逐步降低( p 0 . 001 ， anova ) ； 3 )对阈上10db放电率抑制百分比进行的分析显示，配对神经元之间的最佳频率差越小，相互抑制作用越强( r = - 0 . 545 ， p = 0 . 0006 ) ； 4 )配对神经元之间通过相互抑制作用可表kx硕士学位论文waiaster ’ sthesis现出调谐锐化作用，该作用的效率与频率有关， bf处的锐化作用较低，偏离bf时其锐化作用逐步加强； 5 ）频率锐化作用的效率与bf差有关，随着配对神经元之间的bf差扩亢q10 ， q30值的变化逐渐减小，其变化百分比与配对神经元之间的频率差存在明显相关； 6 ）配对神经元之间的相互易化作用不仅表现在放电率增加上，也表现在频率调谐曲线的扩宽，即频率响应范围扩大。 |
