摘要: 本工作使用36只成年雌性大白鼠,随意分成三组,第一组11只动物接受双侧内嗅区损伤的手术,第二组11只动物作为手术对照,第三组14只动物不作手术,为正常对照。 本工作由两个同时进行的实验组成。(1)观察动物对训练棒的攻击和自卫行为反应,分别计算术前和术后每只动物出现强反应的百分比。(2)开阔场地测试,记录动物在10分钟内走过的方格数,并观察其活动方式。实验结果表明,损伤后,攻击行为、自卫行为的强反应比例和方格数都比术前有显著增加(P<0.001;<0.01;<0.001)。损伤后的动物在两个实验上都有“冻结”、蜷伏、理毛和洗脸等动作的明显减少。在第一个实验中还发现,动物会表现出被训练棒出现的新异视觉刺激强烈吸引的异常现象。分析这些结果,可以了解,大白鼠内嗅区的主要功能之一可能与形成恐惧性情绪因素有关,并因而促进动物活动中的止动反应。在行使这些功能的过程中,视觉因素可能存在着微弱的影响。

Abstract: This work used 36 adult female albino rats which were divided randomlyinto three groups. The eleven rats of the first group suffered bilateral entorh-inal area lesions. The eleven rats of the second group were operated as control.The third one which was made up of 14 rats was normal control group. This work was consisted of two experiments which were performed simu-ltaneously. (1)Observing the rats on the aggressive and defensive bebaviorsagainst a training stick, and at last calculating the percentages of strongerreactions of each rat in pre-and postoperative periods.(2)Placing rat in anopen-field, and recording its walked quodrate numbers in 10min. and observingits performance. The results have indicated, after lesions, the percentagesof stronger reactions in two behaviors and the quodrate numbers were all highersignificantly than that before lesions(P<.001;<0.01;<.001).The lesioned ratsshowed few "Jreezing", crouching, grooming, and washing face in both exper-iments. In the first experiment, we also found that the lesioned rats displayeda phenomenon in which they were attracted intensely by a novel visual stim-ulation, i. e., the presentation of the stick. These results were analysed, then we may suggest that one of the chieffunctions of the entorhinal area in the albino rat is probably related to formingemotional factor of fear, and the?efore promoting the immobility in the actionof the rats. In performing these functions, presumably, visual factor may af--fect this process feebly.
