ABSTRACT
The present study was performed to map efferent projections of the pigeon intergeniculate leaflet (IGL) to other visual structures, with emphasis on the pathways containing neuropeptide Y (NPY). After injections of an anterograde tracer (Phaseolus vulgaris leucoagglutinin) into the IGL, labeled axons and presumptive terminals were seen in several retinorecipient and visually-related nuclei. All such areas contained immunoreactive fibers to antibodies against NPY. Electrolytic lesion of the IGL provoked a marked reduction in the number of NPY-labeled fibers in these visual structures. The data suggest that the IGL is the source of NPY-labeles axons which occur in many visual nuclei of the pigeon brain
