SynEM score thresholds and associated precision and recall. SynEM score thresholds θ chosen for optimized single synapse detection (θs) and optimized neuron-to-neuron connection detection (θnn) with respective single synapse precision (Ps) and recall (Rs) and estimated neuron-to-neuron precision and recall rates (Pnn, Rnn, respectively) for connectome binarization thresholds of γnn = 1 and γnn = 2 (see Figure 5).
