“…Motor neurons in these ganglia control movements of the feeding musculature and associated structures, namely, the radula, odontophore, and corresponding tensor muscles. Neuron 19, a hyperretractor motor neuron, and neuron 110, a retractor motor neuron (Murphy, 2001), are readily accessible electrophysiologically with intracellular recording electrodes through the ganglion sheath (Fig. 2 A).…”

“…Dissection methods have been described previously (Haydon and Zoran, 1991). Two buccal neurons, both of which innervate radular tensor muscle groups (Kater, 1974;Zoran et al, 1989), were used for these studies: neurons 19 and 110 (previously B19 and VB10, respectively; see Murphy, 2001). They were identified based on their size, position, and pigmentation.…”

“…Interestingly, the contraction of the CM is strongly influenced by the degree of satiation of the animal (Balaban 2002). Feeding-induced arousal and food intake in snails are regulated to a large extent by serotonergic 5-hydroxytryptamine (5-HT) and dopaminergic neurons (Murphy 2001, Elliott & Susswein 2002. FMRFamide and FMRFamide-containing pleural neurons both inhibit feeding and facilitate withdrawal behaviour in various gastropod species (Kyriakides & McCrohan 1989, Murphy 1990, Alania et al 2004.…”

“…In Helisoma and Lymnaea, it is possible to define three phases for feeding motor patterns, corresponding to protraction, retraction, and hyperretraction (Murphy, 2001;Elliott and Susswein, 2002). A study of 22 motor neurons in reduced preparations of Aplysia during ingestive-like and egestive-like motor patterns demonstrated that there was a clear boundary between protraction and retraction in the synaptic inputs to the motor neurons, but many subcomponents of the motor output could be distinguished [Church and Lloyd (1994), their Fig.…”
