A team of vision scientists at the University of California, Berkeley and Massachusetts Institute of Technology (MIT) revealed this secret of the human #brain: To save us from insanity induced by a constantly changing torrent of pictures, shapes and colors – both virtual and real world – the brain filters out information, failing in most cases to notice small changes in a 15-second period of time.
It actually means that what we do see is, in fact, a mixture of past and present. According to the research, published in the journal Nature Neuroscience, stability is attained at the expense of accuracy.
“What you are seeing at the present moment is not a fresh snapshot of the world but rather an average of what you’ve seen in the past 10 to 15 seconds,” said study author Jason Fischer, Ph.D., a neuroscientist at MIT.

Although it has a 15-second delay in perception, the brain can also work incredibly fast. Neuroscientists from MIT recently found that even if the eye sees an image for as little as 13 milliseconds, the brain can still successfully process it.
