Perhaps you should try some spelling variations:
functional membranes » functional means, neuronal membranes, functional metrics
functions membrane » functions message, functions mean
functions memory » functions more, connections memory, functions methods

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: ((dys((functions memory) OR (((functions membrane) OR (functional membranes))))) OR (((functions memory) OR (((functions membrane) OR (functional membranes)))))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dys((functions memory) or (((functions membrane) OR (functional membranes))))) or (((functions memory) or (((functions membrane) OR (functional membranes))))))".
• Adding a wildcard symbol may retrieve word variants: ((dys((functions memory) or (((functions membrane) OR (functional membranes))))) or (((functions memory) or (((functions membrane) OR (functional membranes))))))*.
