Figure 3.

Histology of mPFC-BLA disconnection. A, mPFC lesions. B, BLA lesions. Largest lesions (in gray) and smallest lesions (in black) of rats included are depicted here. The unilateral images are representative of lesions in both hemispheres. Brain sections of the mPFC and BLA were stained with 0.1% cresyl violet to verify sites of excitotoxic damage (marked by arrowheads). Note the darkly stained astrocytes and absence of cell bodies in lesioned tissue (4×). C, Intact mPFC. D, Lesioned mPFC. E, Lesioned BLA. F, Intact BLA.
