The mean (+SE) number of Fos-immunoeactive nuclei in different parts of the periaqueductal gray (PAG) at atlas levels (AL; 52) 34 (A), 38 (B), 41 (C), 42 (D), and 43 (E) of euglycemic (open bars) and hypoglycemic (solid bars) animals. No statistically significant differences were apparent between groups at any anatomical level. COM, commissural nucleus, PAG; d, dorsal division PAG; dl, dorsolateral division PAG; m, medial division PAG; PAG, periaqueductal gray; PRC, precommissural nucleus, PAG; rl, rostrolateral division PAG; rm, rostromedial division PAG; vl, ventrolateral division PAG.
