Description

Pelvig et al. studied neocortical glial cell numbers and found that oligodendrocytes decrease 27% over adult life and correlate with total number of neurons while total astrocyte number remained constant. An increase in the number of glial cells with ageing, called gliosis, has also been known to occur in most brain areas, involving primarily the neuroglial cells.
