| Research Abstract |
We investigated auditory responding nuclei in a budgerigar brain, and a relationship between seismosensory recognition of water movement made by a prey and feeding behaviors in sculpins. In the study of budgerigars, we have done two kinds of studies. Firstly, we made a new stereotaxic equipment for fixing the budgerigar brain firmly and identifying exactly the three dimensional coordinates of brain nuclei. The second study was to identify the brain nuclei responding to sound stimuli. The tritium-labeled 2-deoxy-D-glucose was injected into alive budgerigars intra-muscularly. Sound stimuli was applied for one hour through a speaker in a dark sound-attenuated chamber, then brains were removed. As a result, the processed film images showed that there were two ascendeing pathways from the cochlear nucleus in relation to the auditory perception. One was the pathway running via nuclei of MLD and Field L , which does not have any connection to the thalamus. The other was a route via nuclei of

In the research using sculpin as a subject, we proposed to study the relationship between moving of food and feeding behavior of Baikal sculpins and Japanese sculpins. In an experiment using Baikal sculpin, we used live amphipods as a moving stimulus. Presented the live amphipods, Baikal sculpin chased after actively and prey them surely, but for the dead amphipods very little to do so. Furthermore it was determined that the time when subjects chase and prey amphipods most actively is a little after sunset primarily and secondarily shortly before sunrise, indicating that Baikal sculpin has diphasic cycle of activity in a day. In Japanese sculpin, we used an artificial food as moving stimulus which was presented to subjects by being earned in a flow of circulating water. Presented the moving food the subjects oriented themselves to it at high probability and then got it. But once losing sight of moving food, they couldn't find out and also not get it. From results of both species of sculpins, it was clarified that moving of food is essential to success for getting food in sculpin. Less
