Noise in the nervous system
A. Aldo Faisal, Luc P. J. Selen and Daniel M. Wolpert
Abstract
Noise — random disturbances of signals — poses a fundamental problem for
information processing and affects all aspects of nervous-system function. However, the
nature, amount and impact of noise in the nervous system have only recently been
addressed in a quantitative manner. Experimental and computational methods have shown
that multiple noise sources contribute to cellular and behavioural trial-to-trial variability.
We review the sources of noise in the nervous system, from the molecular to the behavioural
level, and show how noise contributes to trial-to-trial variability. We highlight how noise
affects neuronal networks and the principles the nervous system applies to counter
detrimental effects of noise, and briefly discuss noise’s potential benefits.
