Scientists have presented that the average person blinks 15-20 times per minute. That"s as much as 1,200 times per hour and a lining 28,800 time in a day--much more often than we need to keep our eyeballs lubricated. In fact, we spend around 10 percent of our waking hrs with our eye closed.

New research study from Japan"s Osaka University discovered that blinking may serve as a form of momentary rest for the brain, offering the mind a chance to wander and "go offline." These quick breaks might last just a split second, or even a few seconds.
When our brains aren"t concentrated on a task, mind regions recognized as the "default mode network" come alive, enabling our mind to switch into an idle mode--a phenomenon researcher discovered years ago. However how does blinking affect this idle state?
According come the new research, blinking and the brain at rest go hand in hand. In order to know this phenomenon, scientists monitored the brain activity the 20 healthy and balanced subjects in a brain scanner while lock watched snippets of a comedy reel.
The researchers found that in ~ points where herbal breaks emerged in the video, two things happened: the protect against elicited a spontaneous blink in subjects, and the scan verified a emboldened in the locations of the mind that control focus. For the fleeting moment, the default setting network stepped in to take over because that an idle brain.
While our mindful brains may not even detect the stop, the short-lived lapse can provide a wakeful reprieve--although perhaps just for a fraction of a second. This new research may help scientists know the correlation between lying and also blinking patterns--it"s feasible that since lying is one attention-intensive activity, world blink less throughout deception.
