Spatiotemporal pattern of neuronal injury induced by DFP in rats: A model for delayed neuronal cell death following acute OP intoxication

► DFP induced neuronal FJB labeling starting at 4-8 h after treatment ► The pattern of DFP-induced FJB labeling closely corresponded to TUNEL staining ► FJB-positive cells displayed reduced NeuN immunoreactivity ► FJB-positive cells were not immunopositive for GFAP, O4 or ED1 cell markers
