Title:  Activity of Inhibitory Neural Networks Generated by the Small World Paradigm

Abstract:   While the behaviors of excitatory neural networks have been throughly studied, similar networks with inhibitory signaling have not received the same meticulous treatment in the literature. Motivated by future research into hippocampus-like networks, in this talk we will discuss the activity of inhibitory neural networks by analyzing how changing the cell type (Type I vs. Type II) causes nearly antithetical behavior in nearest neighbor networks. Additionally, by utilizing the Small World Network Paradigm famously articulated by Watts and Strogatz, we will see how the behavior changes as we systematically alter the network topology from nearest neighbor to sparse random connectivity. Finally, we will examine the somewhat counterintuitive result that, unlike all-to-all networks, inhibitory networks with sparse random connectivity tend not to synchronize better for lower connection strength and duration of synaptic signaling.
