Figure 2

Examples of tracing in whole mount brain (cortex removed) and retina. (A) left: shows clear anterogradely-transported CTB label in the major retinal targets that include lateral geniculate nucleus (LGN), pretectum (PT), and superior colliculus (SC), other identifying landmarks outside the visual pathway include inferior colliculus (IC) and cerebellum (Cb). (A) right: shows good coverage of the SC with retrograde tracer FluoroGold (FG). (B) left: shows a near complete loss of CTB in the left SC and nearly no loss in the right SC. (B) right: FG covers the SC completely. (C) Illustrates the range of retrograde transport of FG we found, from complete coverage in the leftmost panel, to sectorial loss in the middle panel, and a near complete loss in the rightmost panel.
