Results from a large injection are indicated in the top row; smaller injections and the mean from those smaller injections (“Mean”), are also indicated. Injection sites are characterized by indicating the MG subdivisions included in the injection: X indicates the subdivision with the most tracer, + indicates MG subdivisions that contain tracer. The “other” column indicates minor spread outside the MG. “# retro cells” is the number of retrogradely labeled cells in PMT (bilaterally, every 6th section). The “%ChAT immunopositive” and “%ChAT immunonegative” columns describe the indicated cells as a percentage of ”# retro cells”. FG, FluoroGold. GB, green beads. RB, red beads.
