Anyone learning to drive a car will have experienced how the first (very conscious) fumblings are transformed through constant practice into automatic actions. The neural networks driving those first uncertain fumblings are precisely where we would expect to find nerves in the undecided state when a small nudge from the brain's em field can topple them towards or away from firing. The field will "fine tune" the neural pathway towards the desired goal. But neurons are connected so that when they fire together, they wire together, to form stronger connections. After practice, the influence of the field will become dispensable. The activity will be learnt and may thereafter be performed unconsciously.
