Axonal projections of ganglion cells to the superior colliculus (SC) and to the nucleus of the optic tract (NOT) were re-examined physiologically in the cat's retina. Taking care to minimize current spreads around the stimulating electrodes placed in the NOT or the SC, we reached a conclusion that a substantial proportion of X-cells project to the NOT while a small but definite proportion of them project to the SC.
