Brain at work with every blink.

Research by scientists at UC Berkeley, Nanyang Technological University in Singapore, Université Paris Descartes and Dartmouth College finds that when we blink, our brain repositions our eyeballs so we can maintain our focus on what we’re viewing. When our eyeballs roll back in their sockets during a blink, they don’t always return to the same spot when we reopen our eyes. The brain has to readapt its motor signals to redirect our eyes to where they should be pointing.
