Transitions between beta and gamma rhythms in neural systems.
We study the coexistence of different rhythms in a local network of one inhibitory and two excitatory nerve cells for a wide range of the excitatory synapse strength and of the slow K+-channel conductance. The dynamic features of spike trains in the presence of noise are discussed. It is found that noise can both cause switching between different states and induce coherent firing events.
