Summary of adaptation induced changes of the response curve parameter <i>B</i>₅₀ for all 20 AN2 cells.

<p>Distribution of the mean values of the parameters <i>B</i>₅₀ for individual cells (A1) and combined posterior density (see <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1000182#s2" target="_blank">Methods</a>, Bayesian data analysis) over all cells (A2) after adaptation to the bimodal stimulus distribution. (B1,B2) Distribution and combined posterior density of the parameter <i>B</i>₅₀ after adaptation to the trimodal stimulus distribution. (C1,C2) Distribution and combined posterior density of the change of the parameter <i>B</i>₅₀ between the two stimulus distributions. Symbols depict the values predicted by infomax (stars) and the selective coding hypothesis (circles). Triangles denote the median value. The distribution of cells that showed changes in <i>B</i>₅₀ that were significant (Bayesian posterior intervals, see <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1000182#s2" target="_blank">Methods</a>, Bayesian data analysis) is marked black in (A1,B1,C1). Shaded areas depict the two-tailed 95% posterior intervals in (A2,B2) and the right-tailed 95% posterior interval in (C2).
