we labeled proteins in the cell bodies of rabbit retinal ganglion cells with [ 35s ] methionine and subsequently observed the appearance of radioactive actin in tissues containing the axons and synaptic terminals of these neurons , i.e. , the optic nerve ( on ) , optic tract ( ot ) , lateral geniculate nucleus ( lgn ) and the superior colliculus ( sc ) .
