The brain's 7-D sandcastles

From this article.

"He and his colleagues of the Blue Brain Project at the Swiss Federal Institute of Technology in Lausanne (EPFL) have been using algebraic topology, a field of mathematics used to characterise higher-dimensional shapes, to explore the workings of the brain. What they have found beggars belief. As our brains think, learn and remember, they create elaborate but ephemeral structures in at least seven mathematical dimensions, and possibly many more. What’s more, these transient structures, which appear and disappear like sandcastles on a beach, could help us understand how the brain creates our thoughts and feelings. They might even unravel the greatest mystery of them all: consciousness."
