Perhaps you should try some spelling variations:
rapidly decreasing » rapidly decrease (Expand search), rapidly decreases (Expand search)
decrease rapidly » disease rapidly (Expand search), decrease lipid (Expand search)
decreasing costs » decreasing cost (Expand search), decreasing rest (Expand search), decrease costs (Expand search)
decrease firing » decrease during (Expand search), decreases during (Expand search), decreased during (Expand search)
firing patterns » foraging patterns (Expand search), feeding patterns (Expand search), driving patterns (Expand search)
costs decrease » loss decrease (Expand search), not decrease (Expand search), cells decrease (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 rapidly decreasing costs decrease ) OR ( decrease NOT decrease firing patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease rapidly decreasing costs decrease ) OR ( decrease NOT decrease firing patterns ))*.
