The results showed that:(1) The characteristic frequency of IC neurons of house mouse was increased with increasing recording depth, and the masker intensity used was positive relevant to the IC neurons\' minimum threshold. When the minimum threshold was high, the masker intensity needed was loud, vice versa.(2) According to the masking rate at MT+10dB of IC neurons to frequency modulation and tone burst, the IC neurons were classified as three types: type I neurons ( 72/113, 63.7%), in which the masking effect of TB was better than frequency modulation ;type II neurons (32/113, 28.3%), in which the masking effects of the two maskers were same; type III neurons( 9/113, 8.0%), in which the masking effect of FM was better than TB.(3) Type I neurons, the minimum threshold of which was low, but the Q_(10) and DR values of which were large; in type III neurons, the minimum threshold was high, the Q_(10) and DR values were narrow; in type III neurons, the MT Q_(10) and DR values were in between.(4) Both FM and TB could make the MT of type I neurons shift upward distinctively, but the effect of TB was more significant than FM.(5) The Q_(10) values of type I neurons became narrower under the influence of TB, were unaffected under the influence of FM.
结果显示:(1)小鼠下丘神经元的特征频率随着记录深度的增加而增高,掩蔽声强度与神经元的最小阈值呈正相关,即对高最小阈值的神经元进行掩蔽时需要的掩蔽声强度高,对低最小阈值神经元进行掩蔽需要的掩蔽声强度低:(2)根据调频声(frequency modulation, FM)和短纯音(tone burst, TB)对下丘神经元阈上10dB处反应的掩蔽,将小鼠IC神经元分为三类:Ⅰ类神经元(72/113,63.7%),短纯音的掩蔽效果比调频声更好;Ⅱ类神经元(32/113,28.3%),两者对神经元声反应的掩蔽率相同;Ⅲ类神经元(9/113,8.0%),调频声的掩蔽效果更好;(3)Ⅰ类神经元的最小阈值低、Q_(10)值和动态范围大,Ⅲ类神经元最小阈值高、Q_(10)值和动态范围小,Ⅱ类神经元的最小阈值、Q_(10)值和动态范围介于Ⅰ和Ⅲ类神经元之间;(4)短纯音和调频声都可以使Ⅰ类神经元声反应的最小阈值明显上移,但短纯音使神经元最小阈值的上移更显著:(5)短纯音使Ⅰ类神经元的Q_(10)值变小,调频声使神经元的Q_(10)值增大不显著,短纯音与调频声对神经元Q_(10)的影响差别显著;(6)短纯音与调频声都使神经元的动态范围减小,并且作用显著,但短纯音的效果更显著:(7)短纯音与调频声都使神经元反应的潜伏期延长,效果显著,但TB的延长作用更为显著;(8)随着探测声强度的升高,短纯音和调频声对Ⅰ类神经元声反应的掩蔽率都降低,但在各个探测声强度短纯音的掩蔽率都比调频声高。
