    Abstract:
    Different enzymatic patterns of 5'-nucleotidase and simple esterase have been observed in the diencephalon and mesencephalon of the garden lizard, Calotes versicolor. Most of the brain centers have shown the enzyme activities, ranging from negligible through very strong, in the neurons and neuropil. However, two brain centers, the DLH and NM, were found negative to 5'-nucleotidase. On the other hand, no brain center showed negative picture in the preparations of simple esterase. In general, it has been observed that the enzyme activity dominates in the neurons than the neuropil both for 5'-nucleotidase and simple esterase. The major fiber tracts have shown mild reaction product of 5'-nucleotidase except a solitary fiber bundle, the lateral forebrain bundle, which demonstrated, invariably, strong to very strong enzyme activity; the commissura colliculi superioris was, however, negative for the enzyme activity. On contrary, most of the fiber tracts showed strong to very strong activity of simple esterase. The significance of the distributive patterns of the two enzymes in relation to various brain centers and fiber tracts has been discussed.
