Abstract:
Although typically assumed to degrade performance, sometimes random fluctuations, or noise, can improve information processing in nonlinear systems. While various forms of noise-enhanced processing, such as stochastic resonance, have been observed both in theoretical models of neural systems and in experimental neuroscience, the two approaches have
yet to be fully reconciled [1]. We illustrate why this is the case, using examples ranging from the auditory periphery and somatosensory system, to cortical local field potentials. We also propose that future advances in our understanding of in-vivo benefits of random noise in neural systems will require new experiments to be developed that are based on concrete and precise hypotheses regarding potential computational roles of specific neural systems.
