鼠对前兆性地声记忆反应的研究
A STUDY ON MEMORY RESPONSE OF MICE TO EARTHQUAKE PREMONITORY GEOSOUND
-
摘要: 本文比较研究了小白鼠对主峰频率200Hz的前兆性轰隆声和对粉红噪声的记忆反应。结果表明,小白鼠不仅能对这种地声信号产生明显的记忆反应,而且受训鼠对这种地声信号敏感性显著增高。 1.地声组(Gs.G.)和噪声组(N.G.)穿门反应的时间-强度曲线(TIC)都近似指数衰减。在1——5s內(SPL 10dB)的峰值强度分别为0.71和0.40。对照观察(Con.)的TIC近似随机事件的正态分布,1——5s內的反应强度仅为0.13,11——15s內的峰值强度为0.32。 2.地声组对10dB的地声信号穿门反应的潜伏期为2.450.5s,即比噪声组平均短0.86s;对10——30dB的地声信号穿门反应的潜伏期比噪声组约短2s。 3.地声组穿门反应的群体效应明显增高。以3只鼠和4只鼠的群体穿门反应的比率分別为Con.的1.6倍和2.9倍。 4.地声组的受试动物对250Hz纯音反应的TIC仍接近于对地声信号的反应,而对粉红噪声的反应明显地失去原来的反应特性。Abstract: In this paper, comparative studies on the memory responses of white mice to earthquake premonitory thunders with a main peak frequency of 200 Hz and to pink noise are given. The results show that white mice not only can obviously form memory response to geo-sound signals but the sensibility of trained mice to this kind of geo-sound signals is markedly imporv-cd.1. In geo-sound group (Gs. G.) and noise group (N. G.), the time-intensity curve (TIC) of pass-door reactions both approximate to an exponential altenuation, and the peak intensity within the range of periods of 1-5s (SPL 10 dB) is 0.71 and 0.40, respectively. In control observations (Con.), the TIC approximates to a normal distribution of stochastic events, and rhe reaction intensity within the periods of 1-5s is only 0.13, its peak intensity within the range of periods of 11-15s is 0.32.2. In the Gs. G., the latency of pass-door responses to the geo-sound signal at lOdB is on an average 2450.5s, that is, it is on an average 0.86s shorter than that the N. G.; and to the geo-sound signal at 10-30 dB is shorter than the N. G. by about 2s.3. In the Gs. G., the collective effects of pass-door reaction are obvoiusly improved and the ratio of pass-door rection by the groups of three and four mice is 1.6 and 2.9 times of the Con., respectively.4. In test animals of the Gs. G., the TIC responding to a tone of 250 Hz still approximates to response to geo-sound signal, but the response to the pink noise obviously loses the original reaction properties.
