  Incoming sound is in cochlea and auditory nerve encoded into spike trains. At
the third neuron of the auditory pathway, spike trains of the left and right
sides are processed in brainstem nuclei to yield sound localization
information. Two different localization encoding mechanisms are employed in two
centers for low and high sound frequencies in the brainstem. The centers are
superior olivary nuclei, medial and lateral. This paper contains analytical
estimates of parameters needed in description of auditory coding in sound
localization neural circuit. Our model spike trains are based on
electro-physiological recordings. We arrive to best estimates for neuronal
signaling with the use of just noticeable difference of the ideal observer. We
describe spike timing jitter and its role in the spike train processing. All
parameters are accompanied with detailed estimates of their values and
variability. Intervals bounding all the parameter from lower and higher values
are discussed.
