title: Mapping time.
abstract: Neuronal coding of temporal stimulus features can occur by means of delay lines. Given that neuronal activity is conducted through many parallel axons, there has to be a mechanism guaranteeing minimal temporal dispersion. We argue that plastic changes in synaptic transmission that are unspecifically propagated along presynaptic axons are a basis for the development of delay-line topologies. Furthermore, we show how two populations of afferents form a map of interaural time differences as found, for instance, in the laminar nucleus of the barn owl.
