Perhaps you should try some spelling variations:
decreases brain » decreased brain (Expand search), increases brain (Expand search), decreases brown (Expand search)
decrease costs » decreasing costs (Expand search), decreases post (Expand search), disease costs (Expand search)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (Expand search)
brain decrease » brain decreases (Expand search), brazil decrease (Expand search), strain decrease (Expand search)
in object » an object (Expand search), en object (Expand search), and 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 costs decrease _ decrease ) OR ( decreases brain decrease in object ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease costs decrease _ decrease ) OR ( decreases brain decrease in object ))*.
