That's so clever but sobering. Is that meant to show what happens in MS-type conditions?
I think so. With the loss of myelin sheaths our neurons can no longer communicate. Some animals such as invertebrates do not have myelin, but their axons (the long projection) are so wide that there is little physical resistance for the electrical signal, which can get through. A squid's giant, demylelinated axon is visible to the naked eye.
