Inhibitory interneurons play crucial roles in the regulation of patterns of activity in the hippocampus, and some types are thought to be vulnerable in epilepsy. The connections between excitatory and inhibitory synapses are important for generation of bursting activity in pyramidal neurons. The present study investigates the influences of changes in the connectivity of interneurons on the patterns of bursting in several excitatory connections using a multicompartmental pyramidal cell model. Simulations show that bursting activity depends upon changes in the connectivity of the inhibitory interneuron, and the location of the inhibitory synapses on excitatory neurons.
