YOUR OTHER BRAIN IS ELECTRONIC
Scientists have come to doubt their long-held views that the brain is a network of neurons that communicate by chemoelectrical processes via axons. This is the standard view that the brain is alive with electrical current but it is caused purely as a result of chemical potential differences – positive (+) sodium ions passing through membranes to cause the interior of the neuron to become positively charged or positive (+) potassium ions flooding out of the neuron to cause the exterior to become positively charged. It all looks very chemical to them, and so they are quite content in thinking that this is all that is happening. The action potential once triggered then propagates down the axon like some sort of a snowball effect and then when it gets to the end of the axon it will be passed on to another neuron via a synapse, which again is described in great detail as a chemical transmission of the action potential.
Trouble is none of this is explaining what is happening with the myelin sheath. This is the coating of fatty material on the outside of the axon that acts as an insulator for the axons and is also said to be conducive to speeding up the flow of electricity. In an article in New Scientist (21 Feb 2015) “Meet your other brain” we are told that scientists are now shocked, ‘gobsmacked’ was the actual word used, to find that this myelin sheath is actually increasing or decreasing in real time. They had always assumed that the myelin sheath on the axons forms during development and then remains static as an insulator for the axons, and then as a result of aging processes begins to dwindle, thus bringing on diseases such as Alzheimer’s and dementia.
