Frequently Asked Questions for: The Atoms of Neural Computation
  Based on a survey of the literature, we attempt to answer Frequently Asked Questions on issues of cortical uniformity vs. non-uniformity, the neural mechanisms of symbolic variable binding, and other issues highlighted in (Marcus, Marblestone and Dean. "The Atoms of Neural Computation". Science. 31 October 2014. Vol 346. Issue 6209).
