Figure 4.

Simulated reconstruction errors were introduced into a real network of 201 neurons in mouse visual cortex, taken from manually annotated EM data (Lee et al., 2016). This “core” network has no leaf nodes—that is, each neuron is connected to two or more other neurons. Perturbation models and plotting style are identical to that of Figure 2 except that the splitting model was not applied because neuron process diameter (which is needed by the splitting model to determine split probability) is not present in the ground truth annotations. Neuron scores that deviate from the predominantly monotonic trend are those of neurons with few synapses, as described in the text in section 3.2.
