Perhaps you should try some spelling variations:
"mathematics models of cognitive processing and neural networks" » "mathematics models of cognitive processes and neural networks", "mathematical models of cognitive processing and neural networks", "mathematics modeling of cognitive processing and neural networks", "mathematical model of cognitive processing and neural networks"
"mathematic model of cognitive processing and neural networks" » "mathematic model of cognitive processes and neural networks", "mathematical model of cognitive processing and neural networks", "mathematical models of cognitive processing and neural networks", "mathematics modeling of cognitive processing and neural networks"
"mathematics models of cognitive modeling and neural networks" » "mathematical models of cognitive modeling and neural networks", "mathematics modeling of cognitive modeling and neural networks", "mathematical model of cognitive modeling 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: (((("mathematics models of cognitive processing and neural networks") OR ("mathematic model of cognitive processing and neural networks"))) OR ("mathematics models of cognitive modeling and neural networks")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"mathematics models of cognitive processing and neural networks\") OR (\"mathematic model of cognitive processing and neural networks\"))) or (\"mathematics models of cognitive modeling and neural networks\"))".
• Removing quotes may allow a broader search: (((( mathematics models of cognitive processing and neural networks ) OR ( mathematic model of cognitive processing and neural networks ))) or ( mathematics models of cognitive modeling and neural networks )).
• Adding a wildcard symbol may retrieve word variants: (((("mathematics models of cognitive processing and neural networks") OR ("mathematic model of cognitive processing and neural networks"))) or ("mathematics models of cognitive modeling and neural networks"))*.
