Wilcock GK., Esiri MM., Bowen DM., Smith CC.
The cell density in the Nucleus Basalis in six patients with clinical and histological evidence of Alzheimer's disease and reduced choline acetyltransferase activity in frontal and temporal cortex was found to be in approximately 50% of the cell count in five control subjects.
