Perhaps you should try some spelling variations:
spatial processing » spatial processes (Expand search), signal processing (Expand search), analytical 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)

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: "(( decrease lesions decrease spatial processing ) OR ( decreased brain decrease in decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions decrease spatial processing ) OR ( decreased brain decrease in decrease ))*.
