From: Dynamics of a network of excitatory and inhibitory neurons induced by depolarization block
(A,B) Firing rates of excitatory (blue) and inhibitory (red) neurons. Current injection to the excitatory neurons is increased and decreased slowly as shown by the dotted lines. The network is bistable in (A) and tristable in (B). Note that the network can be in different states for the same current input, indicating hysteresis. (C) Same network parameters as in (B) but current injection to the excitatory neurons is constant to demonstrate that the network activity can be oscillatory during the active state.
