Note: We indicated the level of aromatase expression in the different brain regions (Saldanha et al., 2000), from no aromatase-immunoreactive cells (0) to high level of immunopositive cells (+++). While aromatase cell bodies are not observed in some regions, these regions present aromatase-immunoreactive fibers (F; Peteron et al., 2005)
