Figure 11.

A sample pulse pattern of the synfire chain, with pulses of the inhibitory FS populations transmitted via the PCS. Upper plot: pulses sorted by population, from the bottom: initial stimulus, resultant activity of the first inhibitory FS population before (FS1) and after (FS1_trans) transmission, activity of the first excitatory RS population (RS1), and the corresponding patterns for the second group of populations (compare Figure 8). Lower plot: given spike density and resulting histogram of the stimulus in the upper plot. Parameters are a = 4, σ = 20 ms, FS-to-RS (hardware) delay 10 ms.
