I was interested in the article entitled:  Rapid and Economical Silver
Impregnation Technique to Demonstrate Nerve Fibers, Axons, Neurons, and
Senile Plaques and Neurofibrillary Tangles of Alzheimer's Disease  written
by Garvey, Bigelow, and Carpenter (Children's Hospital of Eastern Ontario)
The procedure describes a pretreatment step.  I wasn't sure if the
pretreatment step was required or if you would perform 1 of the 3 as opposed
to all 3?  Does anyone have an answer, please?
