Relationships among RVM neurons retrogradely labeled from the dorsal spinal cord and immunocytochemically labeled for 5HT and/or MOR1. Table shows the number of retrogradely labeled cells counted in three sections from each of three rats. FG, Number of cells retrogradely labeled with FG; FG+MOR1, number of cells double-labeled for FG and MOR1-ir; FG+5HT, number of cells double-labeled for FG and 5HT-ir; FG+MOR1+5HT, number of cells triple-labeled for FG, MOR1-ir, and 5HT-ir. Numbers in parentheses are the number of ambiguous cases, about which no determination could be made.
