Temporal systemization of cognitive-map acquisition

本研究的目的是寻找认知地图获取的时间系统化的心理物理学方法和生理学方法使用MEG，我们开发了一种启发式算法来定位认知地图获取过程中的MEG测量的神经源。然后，通过心理物理实验和脑磁图实验，研究了在虚拟环境中学习不同地标信息时认知图的变化.我们开发了一种启发式算法来定位认知地图获取过程中MEG测量的神经源.通过心理物理实验，研究了虚拟环境中路标信息在寻路和认知地图获取中的作用.我们发现，获得的认知地图是显着不同的功能定位的地标信息。我们还发现，它是必不可少的成功寻路，以保持有关方向的信息。我们已经开始了MEG实验，以发现认知地图获取的神经机制的时间系统化。实验正在进行中，以收集更多受试者的数据，并得出更具体的结论。

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.
