Brain sizes, surfaces, and neuronal sizes of the cortex cerebri: a stereological investigation of man and his variability and a comparison with some mammals (primates, whales, marsupials, insectivores, and one elephant).

||P.139 right column top paragraph: "The glial cell density (Gl-de) probably does not depend on the brain size. A difference between males and females does not exist. The Gl-de in the gray part of the cortex cerebri is at the range of 30,000-60,000 per mm^3. The Gl-de in primates is possibly lower than in other mammals, yet [investigators] cannot find a statistical significance."
