| 1. | Some applications on fem in the micro loudspeaker modal analysis and the acoustic response simulation are introduced 介绍了有限元法在微型扬声器振膜模态分析以及声响应分析中的一些应用。 |
| 2. | On the other hand , zhou shaoci et al proved that amygdala could effect the acoustic response evoked by click on mgb and cortex level 因此,使用纯音作声刺激,进一步研究杏仁体的效应及意义就显得很有必要。 |
| 3. | The main results are as follows : ( 1 ) firstly we investigated the basic characteristics of the acoustic response of a - i neurons to burst tone 主要实验结果及分析如下: (一)大鼠皮层a区神经元纯音反应的基本特征。 |
| 4. | Exactly why humor causes this acoustic response - - rather than , sya , sweaty palms or any other physiological reaction - - has been lost in the mists of evolution 幽默为什么会引起这种声学反应,而不是手心出汗或其他什么生理反应,其确切原因在茫茫的进化,过程中迷失了。 |

| 6. | The changing of the intensity , frequency , or duration of the pure tone can effect the d ischarge and patterns of the acoustic response of these cortical neurons observed A区神经元的纯音反应与声刺激参数关系密切,纯音刺激的时程、强度和频率都可以影响神经元声反应的放电频数或反应型式。 |
| 7. | The diversity of the acoustic response of a - i neurons and the correlation of their response patterns with the parameters of the pure tone , indicate the complexity of their encoding auditory information 皮层a区神经元声反应型式的多样性以及声反应与声刺激参数的相关性,反映了a区神经元听觉信息编码的复杂性。 |
| 8. | ( 3 ) in recent paper the influence of la stimulation on the acoustic response of a - i neurons has been emphatically studied . the experimental results of 139 neurons showed that the acoustic response of 31 . 7 % neurons was inhibited when la was 在被观察的139个声反应神经元中, la刺激使其中31 . 7 %的神经元声反应受到抑制性影响,纯音所诱发的on反应、 on一off反应、持续性反应以及off反应均可以被la刺激所抑制。 |
| 9. | Q30 values of a - i neurons were within from 0 . 24 to 3 . 36 . the values of q30 can also increase with increasing of cfs of neurons , which indicated that the frequency range of acoustic response of a - 1 neurons widened with increasing of cfs of these neurons 值都有随着神经元cf增高而增大的趋势,这就表明在al区听皮层,随着听神经元cf的增高,神经元的频率选择性能越强,神经元低强度反应的频率响应范围也有增大的趋势。 |
| 10. | However according to the view of acoustics , click includes mixed frequencies , so further studies are necessary to investigate the physiological significance of amygdaloid modulating effect on the ascending auditory information at the cortical level . in this paper we firstly observe the characteristics of the acoustic response of neurons in a - i evoked by pure tone ; then investigate the influence of la stimulation on the acoustic response of these neurons and the physiological significance of such influence ; revea l the neural pathway mediating this effect with the neurohistological method ; and study the neurotransmitter and its receptor participating in this effect 本文采用电生理学方法考察大鼠皮层a区神经元纯音反应特征,观察杏仁外侧核( la )对a区神经元声反应的影响,运用神经组织学方法揭示介导这一影响的神经环路,采用多管微电极记录结合微电泳技术的方法研究参与这种影响的神经递质及受体,进一步探讨了这种调制性影响的生理学意义。 |
