Decision latencies measured at the PN, correlated (Pearson's product-moment) with the cost function, in a grouped arrangement of 10 LNs per glomerulus.

Measurements were taken for different combinations of neurotransmitter release rise rate α and decay rate β (shown in ms−1) on inter-LN synapses. Higher cost function means better response. n = 120 for the case of baseline α−β combination, n = 100 for all other cases; values ±SD; (*) marks significance at p = 0.05 level, (†), at p = 0.01 level, n.s. means the p value is greater than 0.05.
