Perhaps you should try some spelling variations:
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 lipid » increases lipid (Expand search), increased lipid (Expand search)
lipid decrease » rapid decrease (Expand search), ligand decrease (Expand search), limb 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 lipid decrease ) OR ( decrease NOT decrease firing patterns ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not decrease lipid decrease ) OR ( decrease not decrease firing patterns ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not decrease lipid decrease ) OR ( decrease not decrease firing patterns ))*.
