SIGNAL SPEED MATTERS_sandbox

Think of unmyelinated neurons like dirt roads and myelinated ones like paved highways.

Cars can travel a lot faster on a smooth paved highway than on a bumpy dirt road.

  • Nerves transmit electrical signals.
  • These signals travel much faster when a neuron is myelinated.
  • The signals also don’t spread to neighboring neurons when there’s myelin.
  • It’s also why device chargers are coated in plastic: no shock when you touch them.
