Method P.103 bottom paragraph:"The timing and rate of cell growth and development were evaluated for both pre- and postnatal neurones. Indices of growth are portrayed as histograms of cell diameter (Fig.2) and as estimates of the surface area and volume of the soma (Table 1). All neuronal measurements were done with a filar micrometer on the Nissl-stained paraffin sections. The size recorded was the largest diameter of each profile. At least 100 neurones along the length of the nucleus were measured at each stage. Data from either frontal or sagittal planes gave comparable distributions of cell size. It was assumed that this was indicative of a spheroidal shape for their soma. However, it might also suggest that the neurones lack a preferential axis of orientation."
