On the role of different types of glia cells and their function in the brain: [https://www.nature.com/articles/d42473-019-00307-0]
"Microglia, often referred to as the nervous system’s immune cells, monitor neuronal health. They are activated by neuronal injury or infection to produce pro-inflammatory factors (M1 phenotype) or anti-inflammatory factors (M2 phenotype). Maintaining the right balance of anti-inflammatory mediators, which allow tissue repair and healing, and pro-inflammatory mediators, to clear cellular debris and aggregated misfolded proteins, is essential to maintain a healthy brain."

"Astrocytes, the most abundant type of glial cells in the brain, regulate the maturation and maintenance of neuronal function. They are highly sensitive to their environment and respond quickly to injury. Like microglia, they exist in various states of activation. In some cases, they can be neuroprotective, by reducing inflammation and stimulating repair, but in others, they are neurotoxic, promoting inflammation and contributing to neuronal cell death. "

We see that these two types are modulating the effects of conflict resolutions and of alarm reactions in the brain.

"Oligodendrocytes are the glial cells that form myelin sheaths around nerve fibers, which allow rapid and efficient transmission of electrical impulses."

This type is directly connected to the program and theme of the ((Nervous - Myelin Sheath|myelin sheath)) of nerves: Touch is perceived as threatening because it has become a trigger for unreleased pain (from blow, accident, trauma)
