[Neurotransmitters of giant neurons in the African giant snail, Achatina fulica Férussac. IV. Supplemental results].

Following the previous works, we identified recently the twelve giant neurones in the ganglia of an African giant snail (Achatina fulica Férussac), by the pharmacological study of their sensitivities to putative neurotransmitters and derivatives, and by the morphological investigation of their axonal pathways due to the intracellular injection of Lucifer Yellow. The neurones studied were: TAN-2, TAN-3, BAPN, LPPN, LBPN and LAPN in the right parietal ganglion; RPeNLN and LPeNLN in the pedal ganglia; and d-LBAN, d-LBMN, d-LBCN and d-LBPN in the left buccal ganglion.
