Figure 4.

Representative photomicrographs from three separate experiments of FRA-like (A–D) and JunD-like (E–H) immunoreactivity in the hippocampus. The immunostained sections are from rats 6 hr (6 h), 2 weeks (2 w), and 1 year (1 yr) after treatment with kainate. Immunostaining for control from a 2-week (Control) time point is shown. There are no significant differences in the levels of FRA and JunD immunoreactivities between hippocampi 6 hr, 2 weeks, and 1 year after saline injection. Note the long-lasting changes in the intensity of the staining.
