What is the title of this article:

Furthermore, even single neurons appear to be complex and capable of performing computations. So, brain models that don't reflect this are arguably too abstractive to be representative of brain operation; models that do try to capture this are very computationally expensive and arguably intractable with present computational resources. However, having said this, the Human Brain Project is trying to build a realistic, detailed computational model of the entire human brain. It remains to be seen what level of success they can achieve in the time frame of the project and the wisdom of it has been publicly contested, with high-profile scientists on both sides of the argument.
