Have you ever wondered why the scenery in front of us doesn't become blurry when we run, ride bikes, or even drive? Even when moving quickly, the image seen is still clear and stable. Although current camera technology is very advanced, especially sports cameras, which claim to be able to capture clear images in extreme sports, they sometimes still require post-processing, so they cannot match the ability of the human eye. So the question is: how do the eyes achieve clear images while moving quickly? Recently, scientists from the Austrian Institute of Science and Technology (ISTA) have found the answer through a series of experiments. They found that there is a region in the brain specifically responsible for "repairing" visual distortions during movement. This area is like a built-in 'video optimization software', specifically responsible for quickly correcting blurriness caused by movement before visual information is transmitted to other areas of the brain. This magical "anti shake software" is located on the lateral side of the thalamus deep in the brain, called the "ventrolateral geniculate body" (vLGN). Scientists have discovered that it is like a signal "collection master", integrating motor and sensory signals from various parts of the brain. When our eyes or body move, vLGN instantly becomes a 'correction master', able to quickly calculate how to correct visual signals, thus keeping the image we see clear. An interesting metaphor can be used to explain the function of vLGN. Imagine we are watching an F1 racing race. The racing speed is extremely fast, and if captured with a regular camera, the image will become very blurry. In order to reduce blurring, the camera will shorten the exposure time, so that the captured image can be directly broadcasted without post-processing. The function of vLGN is similar to that of this camera, but it is even more powerful. It can not only "deblurr" during motion, but also stabilize the image in real time, allowing us to distinguish between our own motion and the motion of the surrounding world. To study the function of vLGN, scientists had mice "roam" in a virtual reality world while observing the activity of vLGN in their brains under a microscope. It was found that vLGN receives copies of motor commands from the brain and uses these commands to 'repair' visual distortions. Although this study was conducted on mice, the function of vLGN is likely to also exist in the human brain. After all, primates also have similar structures in their brains. This study not only deepens our understanding of how the brain operates, but may also provide inspiration for future visual technologies. For example, to enable future cameras to capture clear and stable images in rapid motion like the human eye, even without the need for post-processing. (New Society)
