Figure 3.

The effects of intraoral sucrose and suckling on the number of Fos-immunoreactive neurons in the cervical (C7-8) and lumbar (L4-5) spinal cord dorsal horn ipsilateral to forepaw (Upper) or hindpaw (Lower) inflammation. The mean numbers of Fos-labeled neurons from superficial (laminae I/II), deep (laminae V/VI), and whole dorsal horn are shown. The open bars show rats with inflammation only, and the filled bars show rats receiving sucrose and suckling after inflammation. Asterisks indicate significant differences between the two groups. ∗, P < 0.05.
