Line 101: ====Cross-correlation in sound localization: Jeffress model==== According to [[Lloyd A. Jeffress\|Jeffress]],<ref>Jeffress, L.A., 1948. A place theory of sound localization. ''Journal of Comparative and Physiological Psychology 41'', 35–39.</ref> in order to compute the ___location of a sound source in space from [[interaural time difference]]s, an auditory system relies on [[Analog delay line\|delay lines]]: the induced signal from an [[ipsilateral]] auditory receptor to a particular neuron is delayed for the same time as it takes for the original sound to go in space from that ear to the other. Each postsynaptic cell is differently delayed and thus specific for a particular inter-aural time difference. This theory is equivalent to the mathematical procedure of [[cross-correlation]]. Following Fischer and Anderson,<ref>Brian J. Fischer and Charles H. Anderson, 2004. A computational model of sound localization in the barn owl ''Neurocomputing" 58–60 (2004) 1007–1012</ref> the response of the postsynaptic neuron to the signals from the left and right ears is given by
