Figure 2.

Performance of spike model parameter estimation when varying signal and noise scenarios. Correlation coefficients between the estimated and original parameters are plotted on the y axis in (A–D). (A) Changes in correlation coefficients between estimated and original amplitude scaling factors with change in (B) (background firing, Equation 26) and (B) Changes in correlation coefficients between estimated and original amplitude scaling factors with change in σ (signal width). (C) Changes in correlation coefficients between estimated and original lags with (B,D) σ. (E) The percentage of spikes unaccounted by the conditional intensity function of variable signal and unified model as a function of (B). (F) The percentage of spikes unaccounted by the conditional intensity function of the variable signal and unified model as a function of σ.
