Perhaps you should try some spelling variations:
"mathematical models of cognitive processinges and neural networks" » "mathematical models of cognitive processing and neural networks", "mathematical models of cognitive processes and neural networks", "mathematical models of cognitive properties and neural networks", "mathematical models of cognitive processesinges and neural networks", "mathematical models of cognitive processinginges and neural networks", "mathematical models of cognitive approachesinges and neural networks"
"mathematical models of cognitive process and neural networks" » "mathematical models of cognitive processes and neural networks", "mathematical models of cognitive processing and neural networks", "mathematical models of cognitive approaches and neural networks"

Try widening your search to All Fields.

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: (((("mathematical models of cognitive process and neural networks") OR ("mathematical models of cognitive wireless and neural networks"))) OR ("mathematical models of cognitive processinges and neural networks")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"mathematical models of cognitive process and neural networks\") OR (\"mathematical models of cognitive wireless and neural networks\"))) or (\"mathematical models of cognitive processinges and neural networks\"))".
• Removing quotes may allow a broader search: (((( mathematical models of cognitive process and neural networks ) OR ( mathematical models of cognitive wireless and neural networks ))) or ( mathematical models of cognitive processinges and neural networks )).
• Adding a wildcard symbol may retrieve word variants: (((("mathematical models of cognitive process and neural networks") OR ("mathematical models of cognitive wireless and neural networks"))) or ("mathematical models of cognitive processinges and neural networks"))*.
