Labeled displaced ganglion cells (DGC's) were observed in chick embryos (day 12 to 18) and hatchings following discrete tectal injections of horseradish peroxidase (HRP). Average DGC diameter was 10 to 15 mu, approximately twice the size of orthotopic ganglion cells. Six to 12 DGC's were found per 15 mu section. These findings conclusively demonstrate a tectal projection for the DGC.
