Minimal Size of Cell Assemblies Coordinated by Gamma Oscillations

Breakdown of strong PING as the number of E-cells receiving strong, time-independent drive is reduced.
Neurons 1–80 are I-cells, and neurons 81–400 E-cells. All E-cells receive stochastic drive. In addition, E-cells receive strong tonic drive, with
(A),
(B),
(C), and
(D). Rhythmicity is largely abolished when
(panel C), but weak PING emerges when
(panel D). In Fig. 13C, the rhythm returns when the strength of the E-to-I-synapses is tripled (panel E).
