Correlation of choline acetyltransferase activity between the nucleus basalis of Meynert and the cerebral cortex.
Choline acetyltransferase (ChAT) activities were measured in the cerebral cortex and the nucleus basalis of Meynert (nbM) of post-mortem human brains from 8 cases with Alzheimer type dementia (ATD) and 5 age-matched control subjects. The lowest ChAT activity was detected in the temporal cortex (Brodmann's area 22) and the nbM in ATD. A significant correlation was found between ChAT activities in the nbM and those in Brodmann's areas 4, 7, 10, 17 and 22. Present results provide evidence of a cholinergic projection from the nbM to the cerebral cortex observed by retrograde or anterograde degeneration studies in animals.
