Perhaps you should try some spelling variations:
visual processing » signal processing (Expand search), minimal processing (Expand search), digital processing (Expand search)
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decreased after » decrease after (Expand search), increased after (Expand search)
decrease visual » decreased visual (Expand search), decrease visceral (Expand search), decreases visceral (Expand search)
after decrease » faster decrease (Expand search), after deceased (Expand search), litter decrease (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decreased after decrease visual processing ) OR ( decrease lesions decrease to decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decreased after decrease visual processing ) OR ( decrease lesions decrease to decrease ))*.
