Olfactory signal modulation by molluscan cardioexcitatory tetrapeptide (FMRFamide) in axolotls (Ambystoma mexicanum).

abstract：:Plants release hundreds of volatiles that are important in interactions with insects or other organisms. However, knowledge is scarce as to which of the compounds are detected by the organism's olfactory receptor neurons. In the present study, single receptor neurons on the antennae of the tobacco budworm moth, Heliot...
