Perhaps you should try some spelling variations:
visual regions » visual response, visual neurons, visual responses
words does » worlds does, word does, works does
worlds do » worlds does, worlds die, worlds das
2008 ice » 2008 nice, 2008 sice, 2008 ide

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: 2008 ice ((worlds do) OR (words does)) primary visual regions.
• Adding a wildcard symbol may retrieve word variants: 2008 ice ((worlds do) or (words does)) primary visual regions*.
