title: [Activity of acetyl- and butyrylcholinesterase of the hemispheres and several subcortical zones of the human brain in prenatal ontogenesis].
abstract: Histochemical investigations of acetyl- and butyrilcholinesterase (AChE and BChE) activity in the cortical plate and in some subcortical areas of the human brain have demonstrated that on the 8th week of the prenatal development of the greatest AChE and BChE activity is observed in the dorsal thalamus, epithalamus and in the ependymal layer of various cerebral parts, the forebrain including. The data obtained, prove previous observations, concerning predominant localization of AChE in the intermediate layer of the isocortex (10 weeks). In a 10-week-old human fetus a total high level of AChE and BChE activity is demonstrated in various nuclei of the thalamus and in subcortical structures of the forebrain (nucl. caudatus, Meynert nucl.).
