A, Simulated random deletion of preBötC neurons wherein the reticular premotor system is modeled as a scale-free network. B, Simulated random deletion of reticular premotor neurons from a scale-free network configuration. Top, Raster plot of 50 preBötC neurons (index 1–50) and 100 premotor neurons that directly project to the XII nucleus (index 51–150). Simulation lasts 800 s in total. Gray bar represents the cumulative laser-ablation phase with the total ablation tally. Each dot on the raster plot corresponds to a spike in a single neuron. Bottom, Running-time spike histogram (spks/ms) computed from the raster plot.
