title: Functional neuroanatomy of the 5-HTergic system in the developing and adult buccal complex of the pond snail, Lymnaea stagnalis.
abstract: Organization of the innervation of the buccal region by 5-HT-immunoreactive (IR) elements was investigated in the pond snail, Lymnaea stagnalis, with special attention to developmental aspects. A gradual maturation is characteristic for the 5-HT-IR muscle innervation, appearing first by late (E80-90%) embryogenesis. It runs parallel with the muscle development and the maturation of the 5-HTergic innervation in the buccal ganglia, peaking by the mid-postembryogenesis (P3) with the presence of a 5-HT-IR network in the buccal mass and rich innervation in the buccal ganglia, including axo-somatic contacts. The whole process seems to match with the appearance of the adult-like feeding (radula protrusion).
