Normalized output functions for SBF model with cosine oscillators. In the absence of any variability in the SBF model, the output functions are almost identical regardless the criterion time (A) and their widths are constant regardless the criterion times (B). In the presence of uniformly distributed memory variability, the width of the output unction increases with the criterion time (C). The width of the Gaussian envelope (dashed line in C) linearly increases with the criterion time both for uniform (solid rhombs in panel D) and normally-distributed criterion times (solid squares in panel D).
