P.12138 left column 3rd paragraph: "Glia are said to be the most numerous cell type in the brain (refs 4,
5) and to be 10–50 times more numerous than neurons in humans
(primary source). Evidence for this assertion, however, is scant. The ratio between
the total number of glial and neuronal cells (glia/neuron ratio) in
the cerebral cortex has been shown to increase with brain size (1,
7). However, the numeric expansion of glial cells relative to neurons
seems to contradict the observation that the neuronal need for
metabolic support remains similar across species (8). Data on how
neuronal and glial cell sizes scale with brain size might help solve
this discrepancy, but such data are lacking in the literature." |
