<div>Brain sectioning. T1, T2, T3, and T4: marker tubes. T1, T2, T3, and T4 show transverse planes at −7.00 mm, −9.00 mm, −10.00 mm, and −11.60 mm rostral to the transverse plane of bregma, respectively. The locations of periaqueductal gray (PAG) and the rostral ventromedial medulla (RVM) in the brain blocks are presented. B1: a brain block containing PAG. B2: a brain block containing RVM.</div>
