title: Odor discrimination in single turtle olfactory receptor neuron.
abstract: To explore the ability of odor discrimination of olfactory receptor neurons, current responses to odorant cocktails were recorded from an isolated olfactory neuron of the turtle. Twenty-five percent of the neurons tested responded to both cAMP-dependent and the IP3-dependent odorant cocktails. Application of the cAMP-dependent (or the IP3-dependent) odorant cocktail to the neuron after an inward current induced by the IP3-dependent (or the cAMP-dependent) odorant cocktail was adapted induced a large inward current in the neuron. The results suggest that at least two different receptors exist in a single olfactory neuron.
