Overview of the relative densities of GFP‐positive fibers in anterior–posterior subdivisions of the PAG in rats injected with AAV‐hSyn‐hChR2‐EYFP in the DMH. −, absence of labeled fibers; ±, very low; +, low; ++, moderate; and +++, high. Distances from bregma (mm) are indicated. dmPAG, dorsomedial PAG; dlPAG, dorsolateral PAG; lPAG, lateral PAG; vlPAG, ventrolateral PAG; vmPAG, ventromedial PAG. The average result for the three rats (in bold).
