MSO precision in dependence on sound frequency and spike timing jitter. (A) Vector strength (VS), in units per cent shown together with the smallest detectable ITD in µs in dependence on sound frequency. Sound frequency 140 Hz used in  is shown by circle. (B) Just noticeable difference of interaural time difference depending on variation of the spike timing jitter. Jagged line: simulated data from , solid line: an exponential fit to the simulations under the assumption of arbitrary time precision in the model circuit, line with circles: a quadratic function estimate of spike timing precision in a system with realistic noise.
