Computational role of mean-encoded signals.

<p>(Top) Representation of periodic mean stimuli in the population rate of noisy, independent neurons. (Left) Representation of step-like mean signals in the population rate of noisy, independent neurons. (Bottom) Common fluctuating currents from presynaptic partners represent a common mean signal that leads to pairwise spike correlation function . (Right) The average voltage before a spike is shaped by the linear mean response. denotes the input current correlation function. The role of the linear response function is indicated by a dashed green line. <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002239#s2" target="_blank">Results</a> obtained in the alternative threshold model are discussed in the indicated Sections of this manuscript.
