Perhaps you should try some spelling variations:
decrease spatial » decrease survival (Expand search), decrease striatal (Expand search), decrease asian (Expand search)
decreases fear » decreased fear (Expand search), decrease fear (Expand search), decreases boar (Expand search)
spatial effect » spatial effects (Expand search), spatial neglect (Expand search), spatial extent (Expand search)
fear decrease » break decrease (Expand search), merr decreases (Expand search), can decrease (Expand search)
decrease and » decreases and (Expand search), decrease in (Expand search), decrease of (Expand search)
decrease toc » decrease of (Expand search), decrease the (Expand search), decreased to (Expand search)
toc decrease » to decrease (Expand search), the decrease (Expand search), not 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 AND decreases fear decrease ) OR ( decrease toc decrease spatial effect ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease and decreases fear decrease ) OR ( decrease toc decrease spatial effect ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease and decreases fear decrease ) OR ( decrease toc decrease spatial effect ))*.
