Potensial aksi adalah aliran ionik positif dan negatif yang bergerak di membran sel. Potensial aksi melibatkan perubahan potensi elektrik pada permukaan sel saraf atau sel otot pada saat terjadi eksitasi.[1] Langkah awal pengolahan informasi indra adalah transformasi energi stimulus menjadi potensial reseptor, lalu menjadi potensial aksi pada serabut saraf. Pola potensial aksi merupakan kode informasi mengenai dunia, walaupun kadang-kadang kode yang disampaikan berbeda dari yang akan disampaikan. Potensial aksi ada pada tiap hewan.
