Figure 6.

Large variation in average neuronal cell mass, but not in average glial cell mass. Main figure, horizontal bars (stacked, non-overlapping) indicate estimated average neuronal (left) and glial (right) cell mass in the cerebral cortex (dark gray), cerebellum (black) and rest of brain (light gray) for each species. Neuronal and glial cell masses are shown on same scale for comparison. Inset, estimated average glial cell masses shown on a larger scale. Values per structure and species are given in Table 5.
