Perhaps you should try some spelling variations:
neuronal processing » neural processing (Expand search), neuronal processes (Expand search), temporal processing (Expand search)
decreased neuronal » decreases neuronal (Expand search), decreased neuron (Expand search), decreased humoral (Expand search)
in decrease » in decreased (Expand search), on decrease (Expand search), pain decrease (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease of (Expand search)
at decrease » rate decrease (Expand search), that decrease (Expand search), and decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease AND decreased neuronal processing ) OR ( decrease in decrease at decrease ))~.
