Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
motor processing » motion processing (Expand search), color processing (Expand search), emotion processing (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
decreases motor » decreases mtor (Expand search), increases motor (Expand search), decreases food (Expand search)
rate decreases » rats decreases (Expand search), rate decrease (Expand search), water decreases (Expand search)
decrease rate » decreased rate (Expand search), decreases rate (Expand search), decrease at (Expand search)
decrease not » decrease of (Expand search), decrease akt (Expand search), decrease at (Expand search)
not decrease » to decrease (Expand search), not increase (Expand search), and decrease (Expand search)

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