Efficient Identification of Assembly Neurons within Massively Parallel Spike Trains

Figure 7

FP rates of SFCu and NoSFC data as a function of the base line level of the spike time randomization (𝑥-axis). Each panel displays the results for a different test statistic ((a): 𝑡^CPC₁, (b): 𝑡^CPC₃, (c): 𝑡^CSF₁, (d): 𝑡^CSF₃). The curves within each panel show the percentage of FPs for different sampling sizes from SFCu (𝑘=200, 500, 2000, of a total of 𝑁=5000 analyzed neurons). False positives are distinguished between FPs from neurons that are members of the embedded chain (FP₁, stars and solid lines) and neurons that are part of the rest of the network (FP₂, diamonds and dashed lines). The magenta curves show the FP rate for 𝑁=5000 randomly selected neurons from a network without an embedded chain (NoSFC).
