Δ<i>x</i><sub>1</sub> refers to the maximum difference between <i>x</i><sub>1</sub> during the LD priming stage and the steady state value of <i>x</i><sub>1</sub> in the absence of any stimulus. Δ<i>x</i><sub>2</sub> refers to the difference between the maximum values of <i>x</i><sub>2</sub> during the HD period with and without priming pretreatment. (B) The time courses of the priming data sets naturally divide into three clusters, corresponding to three priming mechanisms. The pie chart shows the relative frequencies of the priming mechanisms among all the priming parameter sets.</p>
