Histochemical mapping of ATPase and simple esterase in the cerebral hemisphere of the Indian lizard, Uromastix hardwickii.

Adenosine triphosphatase (ATPase) and simple esterase (SE) have been mapped at various levels of the cerebral hemispheres of the lizard, Uromastix. Some areas were intensely positive for one or both enzymes while others were totally negative for both. Variation in enzymatic activity has been observed at different levels in the same nucleus. The functional significance of the findings is discussed.
