Previously it was thought that the neurons were active, but glial cells were only structural and nourishment objects. Apparently glial cells can influence neighboring neurons at least through glutamate signals. Details in the Proceedings of the National Academy of Sciences. Maybe we still have a little more to learn about biology." I know, it's my second 'science question' headline of the day, but heck, most science headlines should end with a question mark.
