The purpose of this research is to find temporal systemization of cognitive-map acquisition by psychophysical method and physiological method using MEG, We developed a heuristic algorithm to localize the neural source from the MEG measurement during cognitive-map acquisition. Then, we investigated change of acquired cognitive map while learning virtual environment with various landmark information by psychophysical and MEG experiments.1. We developed a heuristic algorithm to localize the neural sources from the MEG measurement during cognitive-map acquisition.2. We investigated roles of landmark information for way finding and acquisition of cognitive map in virtual environment by psychophysical experiments.3. We found that acquired cognitive map was significantly different as a function of localization of landmark information. We also found that it was essential for successful wayfinding to maintain information about orientation.4. We have started MEG experiment to find temporal systemization of neural mechanisms for cognitive-map acquisition. The experiment is under way to collect data from more subjects and to find more concrete conclusion.

本研究的目的是利用脑磁图，寻找心理物理方法和生理方法获取认知地图的时间系统化，并开发了一种启发式算法，在认知地图获取过程中从脑磁图测量中定位神经源。然后，通过心理物理实验和脑磁图实验研究了不同地标信息的虚拟环境在学习过程中所获得的认知地图的变化。我们开发了一种启发式算法，在认知地图获取过程中从脑磁图测量中定位神经源。通过心理物理实验考察了地标信息在虚拟环境中认知地图的路径发现和获取中的作用。我们发现，获得性认知地图作为地标信息本地化的函数存在显著差异。我们还发现，对于成功的寻路来说，保持方位信息是必不可少的。我们已经开始了脑磁图实验，以寻找认知地图获取的神经机制的时间系统化。这项实验正在进行中，以从更多的受试者那里收集数据，并找到更具体的结论。
