Cells labeled by rVSVΔG(RABV-G) were observed in the CP, GP, substantia nigra (SN), thalamus, and layers 3 and 5 of the cortex, consistent with infection at the axon terminal and retrograde labeling of cell bodies of neurons known to project directly to the CP (Figure 5C) (Albin et al., 1995). Here, CP is linked to infection.
