Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
lesions decrease » response decrease (Expand search), lesions case (Expand search)
eeg processing » egg processing (Expand search), log processing (Expand search), vog processing (Expand search)
decrease eeg » decrease treg (Expand search), decrease need (Expand search), decrease cell (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 AND decrease eeg processing ) OR ( decrease lesions decrease OR decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease AND decrease eeg processing ) OR ( decrease lesions decrease OR decrease ))*.
