Abstract

FMRFamide (Phe-Met-Arg-Phe-NH2) micropneumophoresis changed bimodally the activity of LPa2, LPa3, PPa2 and PPa3 neurones in fasting and fed Helix pomatia. In fasting creatures peptide application elicited hyperpolarization and decreased the neuronal membrane excitability and responses to tactile stimulation. In fed snails peptide application caused depolarization, decreased membrane resistance and increased the neuronal membrane excitability and responses to tactile stimulation. Neurophysiological mechanisms underlying FMRFamide effects on feeding and defense behaviour are discussed.
