Scientists at University College London have found that parts of the brain are temporarily "switched off" when we blink.
This is one of an interesting set of facts about vision. Our eyes rapidly move around and focus on different parts of the scene in front of us. Yet, we perceive the scene as static and extremely high resolution. The brain is smoothing out the erratic input from our eyes into a continuous perception of the visible world. Even our blinks are filtered out.
If the brain can do all this for vision, it can certainly do the same for perception of thought processes. We perceive consciousness as smooth, continuous, and directed, yet our higher mental processes may not be as smooth and well-integrated as they appear.
