The supportive functions of neuroglia are well-known. They keep the nervous system chemically balanced, clean and firing fast. That’s the very first thing anyone will learn about these types of cells. But does their importance reach beyond just a janitorial system for the CNS?
There is in fact lots of evidence that suggests nervous system function arises from the activity of neuron-glia networks as opposed to the much more wide-held belief of purely neural networks. This summary on NCBI is a good introduction to the way astrocytes influence the transmission of information in the nervous system: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2894949/
Curious: has anybody gone so far to theorize and/or model neuron-glia networks?
