Brain in a vat scenarios in analytic philosophy feature both brains and technological apparatus. The relation between specimens and technology is an interesting aspect of these scenarios, and in order to explore this relation, I contrast here two kinds of scientific collecting practices: the collection of post-mortem brains versus the compilation of digital brain atlases. This contrast highlights a novel configuration of the relation between brains and new information technologies. This new configuration is traced back to the late 1980s, which (...) saw the rise of a new kind of collection of brains, with a markedly different scope and nature: the neuroscience database. Brains are now easily captured in vivo, so that while post-mortem brains were precious and few, scanners provide an embarrassment of riches in the form of terabytes of data. The rise of the virtual brain as a new digital object for research is reliant on the development of new imaging technologies, but also on the growth of computerised tools, informatics, and electronic networks in this field. These developments contribute to an informational turn in scientific research. This article considers what is involved in the shift in type of object, from the scarce, wet, biological brain to a plentiful, digital, virtual one. It discusses the significance of this new object in terms of collections, institutions, and research practices. (shrink)
