FIG. 3.
Lateral mFPI does not cause neuronal cell loss in the infralimbic (IL) cortex. (A) Drawing indicating the relative position of IL cortex.22 cc, corpus callosum; PL, pre-limbic cortex; rf, rhinal fissure. (B) Representative images of NeuN-stained sections showing the neuronal layers of the IL. (C) Summary data showing that the area of the IL measured in sham and mFPI rats (n = 4/group) did not differ between groups. (D) Stereological cell counts of the ipsilateral IL showed that the number of NeuN-positive neurons/mm2 did not significantly change as a result of mFPI (n = 4/group). mFPI, mild fluid percussion injury; NeuN, neuronal nucleus.
