Egg Laying Hormone, aplysia is a neuropeptide synthesized by the bag cell neurons, which contains 36 amino acids and can stimulate egglaying and ovulation in Aplysia via electrical discharge triggering of neurons. Egg-laying hormone of Aplysia induces a voltage-dependent slow inward current carried by Na' in an identified motoneuron[1][2].
