Eye position signals used for coordinate transformations in humans using fMRI

为什么尽管我们在环境中处于连续运动的状态，但我们在脑海中看到的视觉世界仍然静止？我们可以独立地移动我们的身体，我们的头和我们的眼睛，并且仍然“感觉”我们行走的地面是坚实的，我们周围的墙壁是稳定的。 不知何故，我们的大脑能够通过我们的感官接收信息，并通过复杂的神经元网络解释这些信息。 通过使用功能磁共振成像，我们能够研究这些神经元产生的信号，称为传出复制信号。 此外，功能磁共振成像是研究这些传出复制信号如何与大脑各部分的视觉整合所需的工具。

How is it that although we exist in a state of continuous motion in our environment, the visual world we see in our minds eye remains still? We can move our body, our head and our eyes independently and still 'feel' as though the ground we walk on is solid and the walls around us are stable. Somehow our brains are able to take in information through our senses and interpret this information through a complex network of neurons. With the use of fMRI, we are able to study the signals, known as efference copy signals, generated from these neurons. Furthermore, fMRI is the tool required to study how these efference copy signals are integrated with vision in various parts of the brain.
