Web23 Aug 2016 · Near a SNIC bifurcation, noise can cause a system to repeatedly cross a threshold and produce a spike. When operating in the low-stiffness regime, the model … WebWe report a detailed analysis on the emergence of bursting in a recently developed neural mass model that includes short-term synaptic plasticity. Neural mass models can mimic the collective dynamics of large-scale neuronal populations in terms of a few macroscopic variables like mean membrane potential and firing rate. The present one is particularly …
