title: A simple enzyme histochemical method for the simultaneous demonstration of acetylcholinesterase and monoamine oxidase in fixed-frozen sections.
abstract: We describe an enzyme histochemical technique for the simultaneous demonstration of acetylcholinesterase (AChE) and monoamine oxidase (MAO) (Types A, B, or A+B) in fixed-frozen sections. Several regions in the mesencephalon and brainstem were examined for both somatic and neuropil labeling. The results obtained are equivalent or superior to those obtained using previous methods for the individual localization of these enzymes. The simultaneous visualization of AChE and MAO in the same section allows the relationship of the two enzymes to be easily assessed with brightfield microscopy.
