In just four seconds, can you see a bird in this optical illusion eye test?

To supplement what our eyes can detect, our brains often fill in the blanks to give us a full sensory picture of our environment. This is known as perception.

Visual illusions have also been utilized by neuroscientists to investigate the brain's reality perception processes.
