The intracranial ERP group at Yale (McCarthy, Allison, et al.) have done
work in recent years that might pertain to your question. They've
recorded evoked potentials from inferotemporal cortex in humans, and
have found representations for different types of materials. I don't
remember if they looked at 3D representations though.
Stephen Kosslyn has a book on mental imagery that might be useful to
you also.
