Measurement of Short-Time Spatial Activity Patterns During Auditory Stimulation in the Starling

  • Udo Häusler


The field L complex in birds is a highly structured telencephalic area dedicated to auditory processing. It is composed of an thalomo-recipient layer (L2a) surrounded by different types of layered secondary areas arranged in parallel to the forebrain ventricle and the lamina hyperstriatica. It has been described in the pigeon, and the guinea fowl and reaches its highest differentiation in songbirds (Häusler, 1989; Häusler and Leppelsack, in prep; Fortune and Margoliash, 1992, Vates et al., 1996). The field L complex in songbirds has been shown to be tonotopically organized with a tonotopic area that has an increasing bestfrequency from dorsal to ventral (Leppelsack, 1981; Müller and Leppelsack, 1983; Rübsamen and Dörrscheid, 1986). Our attempt was to link the different anatomical areas to physiological response properties Furthermore it is important to see if the different areas do have their own seperated tonotopic organisation or if they form a continuous area only differing in other properties like temporal response patterns.
