In females (a–c; g–i), THC dose-dependently induced Fos immunoreactivity in several structures, as indicated by *symbol under bars that significantly differ from vehicle in that structure. Vehicle-treated rats = white bars, 0.5 mg/kg THC rats = gray bars, 5 mg/kg THC rats = black. Individual rat data is represented with dots. In males (d–f; j–l), data are represented using the same scheme. *p < 0.05, **p < 0.01, ***p < 0.001 as indicated, or adjacent to structure name in Dose main effect without significant post-hoc.
