Analog Versus Digital: Extrapolating from Electronics to Neurobiology

  title={Analog Versus Digital: Extrapolating from Electronics to Neurobiology},
  author={Rahul Sarpeshkar},
  journal={Neural Computation},
We review the pros and cons of analog and digital computation. We propose that computation that is most efficient in its use of resources is neither analog computation nor digital computation but, rather, a mixture of the two forms. For maximum efficiency, the information and information-processing resources of the hybrid form must be distributed over many wires, with an optimal signal-to-noise ratio per wire. Our results suggest that it is likely that the brain computes in a hybrid fashion and… CONTINUE READING
