title: Distribution of NADPH-diaphorase positive somata in the brainstem of the monitor lizard Varanus exanthematicus.
abstract: The distribution and size of presumptive cholinergic somata in the brainstem of the Savanna monitor lizard Varanus exanthematicus were determined using the enzyme histochemical marker NADPH-diaphorase. Numerous neurons were labelled in the lizard brainstem with this technique. A three dimensional computer reconstruction of this population revealed that it shows marked similarity to the laterodorsal tegmental/pedunculopontine tegmental cholinergic cell column, an NADPH-diaphorase positive population in the mesopontine tegmentum of the mammalian brainstem.
