Fig. 4

Performance of the measures in estimating connection type and delays. A Distributions of static FC values measured using XCov for excitatory (green) and inhibitory (blue) cells. B Performance of a classifier in identifying excitatory and inhibitory synapses with simulation length. The decision boundary of the classifier was set to XCov = 0. C Scatter plots of real and estimated delays across cell pairs using XCov (top) and HOTE (bottom). The size of the markers is proportional to the number of pairs having that specific combination of ground truth and estimated delay. The dashed line is the identity line x = y. Black dots far from the identity line correspond to pairs of inferred and ground truth delays that occurred only once. D Correlation between ground truth and estimated delays with simulation length. E Average error in delay estimation with simulation length. All error bars in the figure are SEM across repetitions of the simulation (N = 5)
