Communication consumes 35 times more energy than computation in the human cortex, but both costs are needed to predict synapse number [Biophysics and Computational Biology]

Darwinian evolution tends to produce energy-efficient outcomes. On the other hand, energy limits computation, be it neural and probabilistic or digital and logical. Taking a particular energy-efficient viewpoint, we define neural computation and make use of an energy-constrained computational function. This function can be optimized over a variable that is...
