It is usual that some kind of the extent of information investors have are assumed in the securities market. For example, there are two groups, more informed investors and less informed investors in this market. We add mediam informed investors to these groups. Thus, we divide a market to three parts. We repeated a laboratory experiment many times. Next, We analyzed it how the results changed by an fMRI (functional magnetic resonance imaging) experiment.We found that more domains of the brain in the medium informed investors are activated than other two investors.

在证券市场中，投资者通常被假定拥有某种程度的信息。例如，在这个市场上有两类人，一种是消息灵通的投资者，另一种是消息灵通的投资者。我们在这些群体中增加了了解媒体的投资者。因此，我们把市场分为三个部分。我们把一个实验室实验重复了很多次。接下来，我们分析了fMRI（功能性磁共振成像）实验对结果的影响。我们发现，与其他两种投资者相比，知情投资者的大脑中有更多的区域被激活。
