| Research Abstract |
Participants were exposed several kinds of sounds. Some schematic picture of landscape was projected in front of them. Participants controlled a slider to change angular field of the landscape picture by zooming until they fell the angular have fit to their evoked spatial image induced by some kind of sound stimulation. In the experiment, we found some obvious changes after participant's decision making. Then, we exposed mice to sound stimulation under each of the pleasant and the unpleasant housing conditions. After mice were spent in each of the two conditions for several days, we analyzed some physiological parameters of mice while exposing to a sequence of sound stimulations. Among the parameters, presenting a sound coupled to the pleasant housing condition significantly decreased hart beat rate. In these studies established useful experimental model to understand neuronal mechanisms of emotion in both of human participant study and animal model study of emotional effects.
