New mathematical method reveals structure in neural activity in the brain

Connectomics has been using graph theory for a while, but this is cool. Seems like more algebraic topology methods will percolate in (hah!) over time.

Anyone have a link to actual paper? Without it there's nothing to be said or thought about this.

This method is computationally very intensive. Betti numbers are hard to estimate from data, statistically speaking.
