Fig. 6. Representative pictures of confocal microscopic analyses showing c-Fos–positive cells (red), glutamic acid decarboxylase–positive cells (green), and colocalization of c-Fos and glutamic acid decarboxylase within the same cell. (A ) A lower magnification. (B and C ) A higher magnification. The cell shown in B1–3 is taken from laminar III, which is relatively small, and that in C1–3 from laminar V, which is relatively large.
