查询词典 auditory

Studies on statistical properties of spontaneous spike trains of single auditory nerve have shown that the distributing patterns of interval in spike trains represent Poisson distribution. Since Poisson distribution is one of the simplest stochastic processes, previous studies on spontaneous spike trains of single auditory nerve were performed primarily by assuming them as stochastic processes. Recently, further studies on nonlinear dynamic system show that we have not enough evidence to demonstrate the process, whose distribution of probability density is exponential, is Poisson process.

But some parents love their children掏耳朵, in fact, there are many harmful effects of掏耳朵:掏耳朵, due to laugh and play rough, you may damage the skin of the external auditory canal; as a result of the use of the tools are not clean and can cause acute otitis externa, furuncle or external auditory canal swelling, caused great suffering to the children; may also be an accident, eardrum perforation, causing serious deafness.

可是有的家长总爱给孩子掏耳朵，其实，掏耳朵有很多害处：掏耳朵时，由于嬉笑打闹，可能损伤外耳道的皮肤；由于使用的工具不干净，可引起急性外耳道炎，或外耳道疖肿，给孩子造成很大痛苦；还可能发生意外，穿破鼓膜，引起严重耳聋。

Results CTVE could clearly demonstrate the shape,size,and relation of the normal auditory ossicular chain.A visualization rate of malleus,incus,and incudomalleal articulation was 100%,and was 32% for the stapedial footplate.However,in only 21% could the anterior and posterior crura of stapes be distinguished.Cholesteatoma was found in 12 cases with chronic otitis media,in which CTVE demonstrated varying degrees of destruction of the auditory ossicle.In 1 case with congenital anomaly,ossicle dysplasia was seen.

结果 CTVE能清楚显示正常听骨链的形态、大小及相互关系，锤骨、砧骨及锤砧关节的显示率为100%(38/38)，镫骨底板的显示率为32%(12/38)，只有21%(8/38)可以分辨镫骨的前、后脚；18例中耳炎患者中12例胆脂瘤形成，CTVE上有不同程度的听小骨破坏。1例中耳畸形显示听骨链发育异常。

Results: The satisfactory MPR images of cochlea, bony semicircular canals, internal auditory meatus and other intratemporal structures can be obtained. The SSD images could show some important bony marks of temporal bone and spatial relationships between them clearly. On coronal plane, SSD images can vividly demonstrate the shape and spatial relationships of malleus and incus. A series images were obtained as the virtual endoscope moved from the external auditory canal to the middle ear cavity.

结果：MPR能在不同切面显示耳蜗、半规管、内耳道及面神经管垂直段等结构，显示率为100%；SSD能清晰显示颞骨重要的骨性结构，如内耳门、颈静脉孔等，冠状位切割后的SSD图像能生动地显示锤骨、砧骨的立体形态及空间关系；CTVE可模仿内窥镜从外耳向中耳移动，清晰显示骨性外耳道、鼓室内侧壁及听骨链等结构。

Auditory Brainstem Response, ABR (or Brainstem Auditory Evoked Potentials, BAEP) is a human body physiology parameter at microvolt level. First, we use the TMS320F2812 of TI company, making the signal through D/A transform and high accuracy operational amplifier, and produce the masking white noises, as well as the Tone Burst to be the stimulus. Then, the evoked EEG will be amplified and filtered. At the same time, we use the A/D of TMS320F2812 to collect and process the signals, and get the digital BAEP.

听觉脑干诱发电位(Auditory Brainstem Response，ABR)为微伏级人体生理参量，采用TI公司的DSP TMS320F2812，通过D/A与高精度运算放大器，生成听力级可调整的掩蔽白噪声与短纯音TB进行刺激，同时对诱发脑电进行放大、滤波、并使用TMS320F2812的A/D进行信号采集与处理，得到数字化的脑干诱发电信号。

We use modiolus puncture approach shown by Alder to obtain recordings of discharge signals from single auditory nerve in guinea pig, and adopt digitally controlled system, which is designed on our self to generate complex waveforms, to measure properties of basic acoustically-evoked response of single auditory nerve.

实验在23只豚鼠上进行，运用Alder的蜗轴穿刺法，记录豚鼠听神经单纤维放电，并用自行研制的计算机程控复杂模式声刺激系统，测定听神经单纤维的基本声反应特性。

Previous studies made in our lab indicated that monaural plugging during the critical period of postnatal development would reduce the special sensitivity of the auditory neurons in the contrary auditory cortex of the plugged ear, with the decrease of NMDA receptor density and its subunits expression in the relative cortex of the adult animal.

本实验室以往的研究表明，在生后发育"关键期"内对大鼠施行单耳堵塞，成年后测定显示，堵塞耳对侧中枢神经元听反应敏感性降低，并伴随相关脑区NMDA受体密度的下降，NMDA受体亚单位mRNA表达减弱。
