Washington, January 23:  Almonds are good for human brains, aren’t they? And so does the ‘blinking’ of human eye. Yes, when we blink our eyes our brain works extra hard to stabilize our vision. Who doesn’t want their brain to work well? So let’s go blinking.

According to the study revealed in the journal Current Biology, it said that ‘when we blink, our brain works extra hard to stabilize our, while adding that blinking lubricates dry eyes and protects them from irritants. When we blink, our brain repositions our eyeballs so we can stay focused on what we’re viewing.

The researchers said that when we rollback our eyes during a blink, our eyes don’t return to the original position when we open our eyes. Gerrit Maus, author from Nanyang Technological University in Singapore, said that "This misalignment prompts the brain to activate the eye muscles to realign our vision. Our eye muscles are quite sluggish and imprecise, so the brain needs to constantly adapt its motor signals to make sure our eyes are pointing where they're supposed to.”

During the study the observers sat in the dark room for long rooms and they used to stare at a dot on a screen while infrared cameras tracked their eye movements and eye blinks in real time. During the study every time they blinked, the dot moved 1 cm but the observers failed to notice the shift. At the same time their brains did adjust the dot and learned to reposition the line of vision on the dot. "Even though participants did not consciously register that the dot had moved, their brains did and adjusted with the corrective eye movement," Maus stated.

He said that the findings of the study stated how the brain constantly adapts to changes and adjusts itself. "These findings add to our understanding of how the brain constantly adapts to changes, commanding our muscles to correct for errors in our bodies' own hardware," Maus explained.
