Why Does the Neocortex Have Columns? A Theory of Learning Structure of the World [pdf]
Skeptical. Previously the brain was a machine consisting of drives and pulleys, just like the state of technology of the day.  Now the brain is a computer that runs deep learning models. It would be one thing to just say the cortex has columns.  It's another to go on and model what those columns are doing with linear algebra. The coincidence that this picture emerges at the same time as current fads in tech is too great to ignoreI am more interested in the work that is identifying different kinds of cells e.g place cells
