E. Mengual et al., NICOTINAMIDE-ADENINE DINUCLEOTIDE PHOSPHATE DIAPHORASE ACTIVITY MATCHES ACETYLCHOLINESTERASE-RICH PATCHES IN THE MEDIAL THALAMIC NUCLEI OF THE CAT, Brain research, 625(1), 1993, pp. 165-168
Patches of high nicotinamide-adenine dinucleotide phosphate diaphorase
(NADPH-d) activity were found in the mediodorsal and midline thalamic
nuclei of cats. These patches matched acetylcholinesterase (AChE)-ric
h patches within the medial thalamus, whereas other AChE-rich patches
were NADPH-d negative. There were also patches of NADPH-d activity in
the lateral habenula, but these did not match the AChE staining. These
results suggest that the functional role of discrete thalamic regions
may require the joint presence of AChE and NADPH-d enzymatic activiti
es.
