Photomicrographs of immunopositive PMT cells that project to one IC and both MGs. For each column, the top panel represents labeling after a FG injection in the left MG, the second panel represents labeling after a GB injection in the right MG, the third panel represents labeling after a RB injection in the left IC, and the bottom panel represents immunolabeling for ChAT. All four panels show the same field of view using different filters to visualize the different fluorescent labels. GP 484. A) Cells in the left LDT labeled for FG (top panel), GB (second panel), RB (third panel), and ChAT immunoreactivity (bottom panel). B) Cells in right PPT labeled for the same markers as listed in A. Arrowheads show a cell that contains all four markers. Scale bars = 10 μm. C) Schematic illustrating the two projection patterns shown in A and B. The solid lines indicate the projections of cell A, while the dotted lines indicate the projections of cell B. cIC, contralateral IC; cMG, contralateral MG; iIC, ipsilateral IC; iMG, ipsilateral MG.
