||Abstract: "The optical fractionator method was applied for estimating the total number of motor neurons and the 3D size distribution was estimated using the rotator method in a vertical design."
||P.348 left column bottom paragraph: "When observing the sections at low magnification (×130), clusters of motor neurons in lamina IX are easily observed and encircled. When measured at a higher magnification (×1960) in a pilot study most of the alpha motor neurons appeared to be above 10,000µm^3 and the remaining between 5,000 and 10,000µm^3. Cells smaller than 5,000µm^3 were therefore excluded as they were considered to be either other types of neurons or glia cells. Neurons outside lamina IX were seldom above 10,000µm^3. The neurons above 10,000µm^3 and positioned in the
encircled area are considered to consist mainly of alpha motor neurons."
