| Highly flexible despite hard-wiring: Even slight stimuli change the information flow in the brain Posted: 23 Mar 2012 05:53 PM PDT When looking at an optical illusion that can appear as either one cup or two faces, which do you see first? What we believe we see in one of the most famous optical illusions changes in a split second; and so does the path that the information takes in the brain. Changes in the information processing can be triggered even by a slight stimulus, such as a scent or sound, at the right time.  |
