[Distribution of acetylcholinesterase in different regions of the human brain according to light and electron cytochemical findings].
On the basis of cytochemical studies the author presents some data, concerning the distribution of acetycholinesterase in the structures of human brain nervous tissues on the photo-optical and ultrastructural levels. There were some differences in the distribution of enzymes in the different brain areas. There were also some special traits in the cytochemical reactions to acethylcholinestherase in connection with the processes of postmortal autolysis and the state of the brain taken for studies. It is assumed that there are 2 forms of acethylcholinestherase in the cells--connected and not connected with the membranes. The author discusses some problems of the synaptical and barrier functions of acetylcholinestherase in the brain as well as the functional significance of the cholinergic system of mediation in relation to its distribution in different brain areas.
