过去的研究已经将θ振荡（4-8 Hz范围内的脑电图活动）与啮齿动物和人类的空间导航以及啮齿动物空间信息的编码和检索联系起来。在本研究中，当人类通过虚拟迷宫时，脑电图活动被测量。结果证实了先前的研究结果，即θ事件的频率与迷宫导航的难度直接相关。我们还能够证明θ波发作最有可能发生在迷宫中新走廊进入视野的点，或者在导航错误已经意识到并正在纠正之后。这表明，就像啮齿动物一样，人类的θ事件与空间信息的编码和检索有关。
Past research has linked theta oscillations (electroencephalographic activity in the 4-8-Hz range) to spatial navigation in rodents and humans, and to the encoding and retrieval of spatial information in rodents. In the present study, electroencephalographic activity was measured while humans navigated through virtual mazes. Results confirmed previous findings that the frequency of theta episodes is directly related to the difficulty of maze navigation. We were also able to show that theta episodes occur most likely at points in a maze where new hallways come into view, or after navigational mistakes have been realized and are being corrected. This indicates that, just as in rodents, theta episodes in humans are related to the encoding and retrieval of spatial information.
