Perhaps you should try some spelling variations:
response decreased » response decrease (Expand search), lesions decreased (Expand search), response increase (Expand search)
decrease response » decreased response (Expand search), increased response (Expand search), increases response (Expand search)
decreased brain » decreases brain (Expand search), increased brain (Expand search), decreased in (Expand search)
brain decrease » brain decreases (Expand search), brazil decrease (Expand search), strain decrease (Expand search)
decrease that » decrease the (Expand search), decrease at (Expand search), decrees that (Expand search)
that decrease » that increase (Expand search), that increases (Expand search), not decrease (Expand search)
objects » object (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 response decreased brain decrease ) OR ( decrease that decrease _ objects ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease response decreased brain decrease ) OR ( decrease that decrease _ objects ))*.
