Instead of using reference tags, use:
Text{{ref|Hubel 1962}}
Which will result in:
Text{{Ref|Hubel_1962}}
You can also specify the same parameter via "name"
Text{{ref|name=Hubel 1962}}
Which will result in:
Text{{Ref|name=Hubel_1962}}
If you leave it blank, the "default" reference will be used (never good!):
Text{{Ref}}
Complex cells{{ref|name=Hubel 1962}} and hypercomplex cells {{ref|name=Hubel 1965}}
And will show up in the references as:
<references/>
