Random noise plays a beneficial role in cognitive processing and produces measurable improvement in simulations and biological agents' task performance. Stochastic facilitation, the phenomenon of additive noise improving signal transmission in complex systems, has been shown to occur in a variety of neural contexts. However, neuroscience analyses t...
