How silent is the brain: is there a “dark matter” problem in neuroscience?

Whether there is an underlying neural code that can explain information transfer in the brain has yet to be determined. This paper explores the idea that more neurons than we currently appreciate may live near dormancy and how those quasi-quiescent states contribute to computation in the brain.

A Tradeoff in the Neural Code across Regions and Species

There are a few theories about what makes us intelligent. Brain weight or volume? Neuron size or count? But what about the neural code itself? This paper explores that possibility that humans encode information better than other species, albeit, with some interesting tradeoffs.
