Retrograde transport of horseradish peroxidase from the preoptic-anterior hypothalamic region to retinal ganglion cells in quail.
Horseradish peroxidase was injected in the preoptic-anterior hypothalamic area of intact male quail and reacted with 3,3'-diaminobenzidine and hydrogen peroxide in eye sections. Cells labelled with peroxidase reaction product were found in the ganglion layer of the retina. One possible function of such retinal-hypothalamic connections might be to participate in the photosexual reflex.
