Example activity of the generative model’s PN-KC network.

<p>Y axis represents instantaneous firing rate, X axis is time. (A) Activity of 20 sample PNs that all connect to the same KC, showing epochs of excitation and inhibition. The shaded area is the onset sequential phase; the rest is the steady state phase. (B): Activity of the KCs during the onset sequential phase where each colored line represents a cluster of three KCs. In total, 15 KCs are shown (five clusters), with maximum firing rates around times t1, t2, t3 and t4. As in <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1004528#pcbi.1004528.g003" target="_blank">Fig 3</a>, the baseline shown is calculated as half the activity level of a PN when only one KC of those connected to it is active.
