## Abstract Innate fear stimulus induces activation of neurons containing the neuronal nitric oxide synthase enzyme (nNOS) in defensive‐related brain regions such as the dorsolateral periaqueductal gray (dlPAG). Intra‐dlPAG administration of nitric oxide synthase (NOS) inhibitors and glutamate anta
