Figure 4

Fos protein expression in the spinal trigeminal nucleus after TASM ligation. a. Low power photomicrograph of a section of the upper cervical dorsal horn illustrating induction of Fos-LI in superficial laminae (dashed rectangle). Scale = 0.2 mm. b. Histogram illustrating mean number of Fos-positive neurons in superficial laminae of Vc-C1 ipsilateral to TASM ligation (TL). Naive rats were used as a control. *, p < 0.05 vs. naive, n = 3/group. Error bars represent S.E.M. c-h. Examples of Fos-LI. All fields were taken and enlarged from a portion of medial-intermediate superficial dorsal horn as shown by the rectangle in a. Scale = 0.05 mm.
