title: [Sensitivity of crayfish muscle fibers to glutamate and to natural transmitter in low calcium solutions].
abstract: The response of crayfish muscle fibres to glutamate, a putative transmitter at its excitatory motor synapses, decreases when extracellular calcium is reduced, whereas the sensitivity to natural transmitter s not modified. Three possible mechanisms are proposed.
