Neuroscientists Olaf Sporns of Indiana University, Giulio Tononi of the University of Wisconsin, and Rolf Köttler of Heinrich Heine University, Düsseldorf, Germany, published "The Human Connectome: A Structural Description of the Human Brain," PLoS Computational Biology I (4). This paper and the PhD thesis of Patric Hagmann from the Université de Lausanne, From diffusion MRI to brain connectomics, coined the term connectome:
In their 2005 paper Sporns et al. wrote:
"To understand the functioning of a network, one must know its elements and their interconnections. The purpose of this article is to discuss research strategies aimed at a comprehensive structural description of the network of elements and connections forming the human brain. We propose to call this dataset the human 'connectome,' and we argue that it is fundamentally important in cognitive neuroscience and neuropsychology. The connectome will significantly increase our understanding of how functional brain states emerge from their underlying structural substrate, and will provide new mechanistic insights into how brain function is affected if this structural substrate is disrupted."
In his 2005 Ph.D. thesis, From diffusion MRI to brain connectomics, Hagmann wrote:
"It is clear that, like the genome, which is much more than just a juxtaposition of genes, the set of all neuronal connections in the brain is much more than the sum of their individual components. The genome is an entity it-self, as it is from the subtle gene interaction that [life] emerges. In a similar manner, one could consider the brain connectome, set of all neuronal connections, as one single entity, thus emphasizing the fact that the huge brain neuronal communication capacity and computational power critically relies on this subtle and incredibly complex connectivity architecture" (Wikipedia article on Connectome, accessed 12-28-2010).
