Brain regions where no projections were found are not included in the table. Areas in which projections occupy 2–20% or <2% of the region of interest were defined as dense or sparse projection areas, respectively. To quantify the number of infected cells that are mCherry-positive, the area of each brain region was measured in ImageJ, and the number of cells within that region was counted. Brain regions were labeled according to the cell density; regions with 1–20 cells per 1 mm2 were classified as containing few cells (c) and those with 20–110 cells per 1 mm2 were classified as containing many cells (cc). c, Few mCherry+ cells; cc, many mCherry+ cells; +, sparse mCherry+ projections; ++, dense mCherry+ projections.
