Perhaps you should try some spelling variations:
decrease lesions » disease lesions (Expand search), decreased response (Expand search), decrease adhesion (Expand search)
eeg processing » egg processing (Expand search), log processing (Expand search), vog processing (Expand search)
lesions case » lesion case (Expand search), lesions caused (Expand search), lesions based (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)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), of decrease (Expand search)
case eeg » case be (Expand search), case el (Expand search), case et (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 lesions case eeg processing ) OR ( decrease NOT decrease toc decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease lesions case eeg processing ) OR ( decrease not decrease toc decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease lesions case eeg processing ) OR ( decrease not decrease toc decrease ))*.
