1) Depolaristion

  • Neurone stimulated
  • Change in PD = change of Na+ gates shape, opening some of the V-D Na+ channels
  • Na+ flows in = depolaristion increases = triggers more gates to open therefore depolarisation increases further

'positive feedback'

  • Rapid opening of all of the Na+ gates
  • No way of controlling the
