Perhaps you should try some spelling variations:
decrease further » increase further (Expand search), disease further (Expand search), decrease the (Expand search)
further decrease » further increase (Expand search), faster decrease (Expand search), the decrease (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)
decrease cell » decreases cell (Expand search)
cell decrease » cells decrease (Expand search), cells decreases (Expand search), will decrease (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)

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 NOT decrease cell decrease ) OR ( decrease further decrease firing patterns ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease cell decrease ) OR ( decrease further decrease firing patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease cell decrease ) OR ( decrease further decrease firing patterns ))*.
