Often we think about the brain as biology, and thus as a piece of nature in the midst of everything in the human. However, recent years of research have shown how our habits and actions enter into the structure and function of the brain. This applies in everything from language and music to meditation and technology. Thus, there is a picture of the "cultural brain" that is shaped by the contexts in which we form part, and it is in some classic notions about the relationship between nature and culture and between heritage and the environment. I will illustrate some of these examples. And open the question: What do they do to our notion of ourselves?
