Interesting. In the background, crucially, is the understanding that 'Memory' is a convenient noun for possibly hundreds of subsystems, or, hundreds of different levels of memory. This research refers to a subcategory of visual recognition memory. What is exciting about the background conceptualisation of memory as a dynamic emergence of interacting simple systems is that when added to this way of seeing all of brain activity, e.g. the classical deadwoods of perception, emotion, motivation etc, the need for complexity theory approaches to neurophysiology contributes to the demolition of classical cognition and heralds the beginning of a leap to not only new understandings of mind but to new consciousness and cognition too.

I agree. If you are interested in models of memory, here is an interesting link: On Intelligence. The book with the same name is highly recommended.

Additionally, living systems and whole ecologies can be described as complex multi layered multidimensional memory systems.
