The symbol ‘O’ stands for the point contact equivalent circuit model parameters fixed at values obtained from sub-threshold optimization of the model parameters for the neuron-electrode interfaces. The fractional surface area of the attached membrane is reported as a percentage of the total membrane surface area; all resistances are in gigaohms (GΩ) and the capacitances are in picoFarads (pF). ‘Sub’ and ‘Sup’ refer to sub- and supra-threshold stimulations respectively.
