Fig. 1From: Approximate, not Perfect Synchrony Maximizes the Downstream Effectiveness of Excitatory Neuronal EnsemblesE-I networks without (left) and with (right) tonic inhibition of the E-cells. The tonic inhibition reduces the number of E-cells participating from 145 to 111. At the same time, the frequency of the rhythm drops from 61 Hz to 47 Hz, and the time that it takes for the first 100 E-cells to fire on each spike volley rises from about 2.9 ms to about 4.4 msBack to article page
