Minimal Size of Cell Assemblies Coordinated by Gamma Oscillations
Figure 7
A simulation similar to that in Fig. 6, but with heterogeneity in drive to the E-cells, and with sparse, random E-to-I-synapses.
The heterogeneity in drive to the E-cells is 10% (see paragraph surrounding Eq. S8 in Text S1). E-to-I-connections are removed with 50% probability, and those that are not removed are doubled in strength to preserve (see Text S1, Section B). Top to bottom:
, 0.05, 0.02
. The rhythm in the I-cells seen in panel C is based entirely on the interaction of the I-cells, i.e., it is an ING rhythm [11]; see Text S1, Section F.
