On Cognitive ability of circumstance of Fish and Birds with visual or auditory oscillation stimuli.

在2004年以金鱼为研究对象，测定了金鱼对垂直条纹的顺时针和逆时针方向10度左右倾斜的阈值，并对金鱼的视觉和听觉振荡刺激进行了研究。我们也开始使用PDA将常用仪器改进为新仪器。2005年，我们尝试了金鱼在区分不同角度和方向的倾斜条纹时，角度策略和方向策略的分离。但我们不能成功地确定分离。此外，我们继续改进新设备。在2006年，我们考察了金鱼视觉辨别学习的新装置。在辨别垂直和水平条纹的任务中，10条金鱼中有3条能在连续3天内通过80%以上正确反应的标准。这3名受试者接受下一个任务的训练，区分垂直和顺时针45度条纹。三分之二可以达到标准。在以虎皮鹦鹉为实验动物的研究中，我们尝试用Zenk蛋白免疫学方法来确定鸣唱感知中枢。2004年，女性被试的枕叶NCM高听区被确定为中心，2005年，额叶NF高听区被认为对歌曲没有反应。在2006年，发现尾侧大脑的高级听觉区与其他鸣禽一样对鸣叫做出反应。在NMR和CMM上，雄性动物对雌性动物“叫声”的听觉区也被确定在大脑尾侧区。

In this study, we attempted to clarify the characteristics of cognitive ability on circumstance of Fish and Birds with visual or auditory oscillation stimuli.In the study with goldfish, in 2004 we determined the threshold of 10 degree in either side slopes, clockwise and counterclockwise, against vertical stripe. Also we began to refine the usual apparatus to new one using PDA. In 2005, we tried the separation between angle strategy and direction strategy of goldfish when discriminating among various incline stripe with various angle and direction. But we could not determine successfully the separation. Also we continued the refinement of new apparatus. In 2006, we inspected the new apparatus for goldfish to perform the visual discrimination learning. In the task of discrimination between vertical and horizontal stripes, 3 of 10 goldfish could clear the criterion of more than 80 % correct responses in 3 continuous days. These 3 subjects were trained next task, discriminating between vertical and clockwise 45 degree stripes. Two of three could achieve the criterion. It may suggest that the new apparatus was useful for discrimination learning of goldfish.In the study with budgerigar, we tried to identify the center of song perception using the immunological method with Zenk protein. With female subjects, in 2004 higher auditory area in occipital : NCM was identified as the center, and in 2005 higher auditory area in frontal : NF was suggested not to respond on song. In 2006, higher auditory area in caudal cerebrum was identified to respond on song like other songbirds. The auditory area of male for female "call" was also identified at NMR and CMM in caudal area of cerebrum.
