CCK and GAD67 positive neurons in each brain region of OLETF rats. Representative immunofluorescent images of the basolateral amygdala (a, b, and c), cornu ammonis area 2 (d, e, and f), and prelimbic cortex (g, h, and i) of OLETF rats. Labeling for CCK (a, d, and g) and GAD67 (b, e, and h) and merged images (blue for DAPI; c, f, and i). Arrows and arrow heads indicate CCK and GAD67 double positive neurons and CCK single positive neurons, respectively. Scale bars = 50 µm. CCK: cholecystokinin; GAD67: glutamate decarboxylase 67; BLA: basolateral amygdala; CA2: cornu ammonis area 2; PL: prelimbic cortex
