Hippocampal theta and gamma rhythms often occur together. While gamma activity is supposed to be generated intrahippocampally, the source of theta oscillations is still debated. Here, a network model of hippocampal inhibitory interneurons was capable of generating the gamma rhythm when responding to constant excitation. Adding a periodic term to this stimulation resulted in complex pattern generation of the network, also including a theta frequency periodicity in the time dependent network coherence measure. A pyramidal cell model driven by the output of this network proved that membrane potential oscillations in the theta range can be entrained by this intrahippocampal mechanism.
