Fig. 6: The number of active KCs but not their spiking rate determines stereotypy.
From: Multiple network properties overcome random connectivity to enable stereotypic sensory responses
a–c Stereotypy in total KC response (a), average number of active KCs (b), and the average rate of active KCs (c) versus the mean spiking rate of PNs. In this set of simulations, the mean spiking rate of PNs was changed by changing the PN spiking range to the indicated mean ± 10. Note that in these simulations, both the average number of active KCs and their average spiking rate increase with the increase in mean PN spiking rate. d–f Stereotypy in total KC response (d), average number of active KCs (e) and the average rate of active KCs (f) versus the number of KCs in the model, when this number was changed to the indicated value in a separate set of simulations. Note that in these simulations, only the average number of active KCs but not their average spiking rate increases with the number of KCs. g, h Stereotypy in total KC response (g) and the rate of active KCs (h) versus the average number of active KCs in two sets of simulations described in the previous panels. Stereotypy increased equally in both sets of simulations with the number of active KCs and did not depend on the average spiking rate of KCs, which increased in the first set but not in the second set. In all panels, n = 100 iterations; in each iteration, averages were taken over both odors and both individuals. Error bars represent s.e.m.
