When glial cells were finally identified and studied, estimates said there might be as many as 9 or 10 glial cells for every neuron. This also appears to be a myth. Christopher von Bartheld at the University of Nevada has outlined some corrections in the Journal of Chemical Neuroanatomy. With the advent of more modern research techniques such as isotropic fractionation, this estimate now appears to be inaccurate. Pioneering work by Brazilian neuroscientist Suzana Herculano-Houzel using this new technique has established there are roughly equal numbers of glial cells and neurons. The concept that glial cells are not more abundant than neurons in human brains is now becoming increasingly accepted in the field, This means more revisions to texts and articles to present the updated findings about glial cells.
