(a) Eye-displacement amplitude, and (b) peak eye velocity, as a function of the input current’s population size for stimulation at sites corresponding to T = 15, 20 and 30 deg. Beyond the default input population size of σpop = 0.5 mm (red symbols), the eye displacement amplitude and peak eye velocity are nearly independent of stimulation strength, while below 0.5 mm they both systematically decrease with decreasing input size. (c) Eye-displacement amplitude, and (d) peak eye velocity, as a function of the input current’s temporal parameter at sites corresponding to T = 15, 20 and 30 deg. The input currents generate fixed number of spikes at SC layer. Whereas the eye displacement remained invariant, peak eye velocity increased with β: the shorter the input duration (large β), the higher the velocity.
