Retinal topography of the neonatal crossed aberrant exuberant projection to the inferior colliculus in the pigmented rat.
The retinal topography of the neonatal transient projection to the inferior colliculus was investigated in pigmented rats by injecting the retrograde fluorescent tracer Fast Blue into the colliculi. The results show that the projection arises from a small population of ganglion cells scattered across the entire contralateral retina, and that the transient projection is therefore not merely an overshoot of axons from the peripheral nasal retina whose appropriate target is the caudal pole of the superior colliculus.
