Correlated variability between SPs and granule cells influences noise correlations.

Abstract

<p><b>A</b>) Noise correlation coefficient as a function of the input noise correlation coefficient <i>c</i> for the SP cells and of the fraction of shared noise with the SPs <i>e</i> for local stimulation. <b>B</b>) Noise correlation coefficient as a function of <i>c</i> and <i>e</i> for global stimulation. <b>C</b>) Reduction (local-global) in noise correlation coefficient as a function of <i>c</i> and <i>e</i>.</p
