The Ecology of Humans (26-28) Glia Activity


Neural activity resembles a communication conduit: electrical signals flowing down axons to a chemical juncture, where a neuron either fires off a signal to neighbors or doesn’t. Glia are more complex: communicating through connected subnets of cells via calcium ion waves. Glia signal nerve cells and receive neural input. Glial waves correspond with the rhythmic pulses that constitute the physiological semblance of awareness.
