But in fact, humans blink about 15 times per minute on average. Have you ever missed anything because you blinked? Probably not. Why is that? According to a new study published in the journal Current Biology in September, our brain has the ability to skip the temporary darkness when we blink. It can keep visual information for a short period of time and then put it together to form an image without interruption. In order to understand how this works, a group of scientists at the German Primate Center and the University Medical Center Göttingen in Germany conducted an experiment. In the study, the participants were asked to look at patterns on a screen whose direction could be interpreted in different ways, such as horizontally(水平地) or vertically(垂直地). When one pattern was about to disappear and the next one was about to come, the participants had to indicate the direction that the next pattern would appear. The researchers found that when the directions of two patterns didn't match, the area in our brain which is responsible for visual memory was activated. This same area showed less activity when two patterns were in the same direction. “The medial prefrontal cortex (额叶皮层) adjusts current visual information with previously obtained information, and thus enables us to perceive the world with more stability, even when we briefly close our eyes to blink，” Caspar Schwiedrzik explained in Science Daily. He is the first author of the study and also a scientist at the German Primate Center. 1．We don't miss anything when blinking because our brain can ________.
