Representative images of staining of 10% formalin-fixed, paraffin-embedded, $10\text{-}\mathrm{\mu }\mathrm{m}$ sections of the fimbria, fornix, and internal capsule for general cellularity by hematoxylin and eosin (H&E); myelin by Luxol fast blue (LFB); microglia by ionized calcium binding adaptor molecule 1 (Iba-1; 1:2,000; Wako Chemicals, see arrow); and astrocytes by glial fibrillary acidic protein (GFAP; 1:7,000, Dakocytomation, see arrow) from female Macaca fascicularis following prolonged exposed to domoic acid ($0.15\text{-mg}/\mathrm{kg}\text{\hspace{0.17em}BW per day}$) or vehicle (5% sucrose). $\text{Scale bar}:100\mathrm{\mu }\mathrm{m}$.
