Perhaps you should try some spelling variations:
response decrease » response defense (Expand search)
decrease response » decreased response (Expand search), increases response (Expand search), increased response (Expand search)
fear processing » pear processing (Expand search), fur processing (Expand search), after processing (Expand search)
decrease faster » decrease after (Expand search), decrease further (Expand search), decreased after (Expand search)
faster decrease » rate decrease (Expand search)
decrease fear » decreased fear (Expand search), decrease fetal (Expand search), decreased heart (Expand search)
decrease to » decreased to (Expand search), decrease toc (Expand search), decrease the (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 to decrease fear processing ) OR ( decrease faster decrease response decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease to decrease fear processing ) OR ( decrease faster decrease response decrease ))*.
