We report here evidence that the pedal peptides (Peps) first discovered in mollusks may be neurotransmitters with a general role in control of molluscan somatic and visceral muscles. Using Tritonia peptide (TPep) antiserum we obtained morphological evidence for such a role in Helix aspersa. We localized 1,200-1,400 small and medium-sized (5-40 microm) TPep-IR neurons in the central nervous system of Helix and demonstrated the presence of these neurons in each ganglion. Many TPep-immunoreactive… CONTINUE READING
