Metaplasticity and the human becoming: principles of neuroarchaeology.

Important recent developments in brain and cognitive sciences offer new avenues for productive cooperation between archaeology and neuroscience. Archaeologists can now learn more about the biological and neural substrates of the human cognitive abilities and use that knowledge to better define and identify their archaeologically visible traces and possible signatures. In addition, important questions and prevailing assumptions about the emergence of modern human cognition can be critically reviewed in the light of recent neuroscientific findings. Thus there is great prospect in the archaeology of mind for developing a systematic cross-disciplinary endeavor to map the common ground between archaeology and neuroscience, frame the new questions, and bridge the diverge analytical levels and scales of time. The term "neuroarchaeology" is introduced to articulate this rapidly developing field of cross-disciplinary research, focusing on questions and problems that emerge at the interface between brain and culture over the long- term developmental trajectories of human becoming. Neuroarchaeology aims at constructing an analytical bridge between brain and culture by putting material culture, embodiment, time and long term change at center stage in the study of mind. This paper presents a critical overview of this new research field and introduces the notion of "metaplasticity" to describe the enactive constitutive intertwining between neural and cultural plasticity. In this context, I summarize the main objectives, cross-disciplinary links, and theoretical grounding of this new approach to the archaeology of mind and outline some of the foundational issues and methodological challenges such a project might face.
