p col≈ 1 – e N – 1–( )T p f,which is very close to the estimation by the Poisson model when N → ∞ .If the average firing rate of every neuron except the winner is the same:f 2= f 3= … = f N= fThe collision rate of the winner isp cw= 1 – ( 1 – T pf ) N – 1IfT p f « 1,N » 1 , we obtain thatp cw≈ 1 – e N – 1–( )T p f• ThroughputThe throughput of the communication channel isN∑S = ϕ i( 1 – ϕ j)i = 1∏j≠i5.7.3 Simulation resultsWe do computer simulations forT p = 0.01. The average firing rates and collisionrates are measured and listed in Table 2 of the appendix. According to the results, as θincreases, the collision rate decreases and the normalized equivalent recurrentstrengths become closer to one. Consequently, the response time is no longer dominatedby the collision rate but the neural latency.60
