Baseline membrane potential, Averaged over 0.5 s before stimulation; Input resistance, the slope of the I-V curve; Maximal voltage response, maximal value of the voltage trajectory; Maximal firing rate, calculated from the PSTH using 100 ms bins; Time constant of the decay in firing rate, calculated by fitting an exponent to the PSTH (1 s bins) starting at maximal value; Duration of the firing response, poststimulus time of the last spike, which was not preceded by >3 s without spikes.
