when impulse activity in the retinal ganglion cell axons is blocked by repeated intraocular injections of the sodium channel-blocking agent tetrodotoxin ( ttx ) throughout the postnatal period of ganglion cell death , the preferential loss of the incorrectly projecting ganglion cells does not occur in the activity-blocked eye , although , as reported elsewhere , the overall loss of ganglion cells is comparable to that seen in normal animals .
