The Expression Patterns of c-Fos and c-Jun Induced by Different Frequencies of Electroacupuncture in the Brain

Figure 2

The nuclei (areas) locations used for the c-Fos-IR and c-Jun-IR counts and the representative c-Fos-IR and c-Jun-IR neurons in AB. P16: NTS at interaural levels of −16 mm. P12: NRM and GI at interaural levels of −12 mm. P5: PBN and LC at interaural levels of −5 mm. A4: the caudal ventrolateral periaqueductal grey (PAG) at interaural levels of 4 mm. A13: the pars compacta of the substantia nigra (SNC) at interaural levels of 13 mm. A15: the nucleus habenula lateralis (HL) at interaural levels of 16 mm. A24: PVH, VMH, ARC, and nucleus amygdala basalis (AB) at interaural levels of 24 mm. A28: SON at interaural levels of 28 mm. A32 shows ACB, the area septalis lateralis (ASL), and CAU at interaural levels of 32 mm. (a1)–(a5) show positive c-Fos-IR neurons in AB in the blank control and at 0, 2, 60, and 100 Hz, respectively. (b1)–(b5) show positive c-Jun-IR neurons in AB in the blank control and at 0, 2, 60, and 100 Hz, respectively. (c) shows the negative control. The bars = 100 μm.
