... will impair olfaction. We performed electro-olfactograms on juvenile gilt-head seabream ( Sparus aurata ) and measured the response to three amino acids at five different concentrations (1×10 −7 to 1×10 −3 mol l −1 ) in normoxic (20 kPa O 2 ) and two hypoxic conditions (12.5 and 5.7 kPa O 2 ). For the first...

... and metabolic states. While this is relatively well studied in mammals, little is known about how internal state impacts olfaction in fishes, the largest and most diverse group of vertebrates. Here we apply electro-olfactograms (EOGs) in the African cichlid fish Astatotilapia burtoni to test the hypothesis...

... labeling techniques. Electro-olfactogram (EOG) recording methods established the relative stimulatory effectiveness of these odorants as: spermine >>spermidine ≈ agmatine > glutamine > putrescine ≥ cadaverine ≥histamine > artificial freshwater. The detection threshold for the potent...

...S. H. Rolen; P. W. Sorensen; D. Mattson; J. Caprio SUMMARY Electrophysiological responses of goldfish olfactory receptor neurons(ORNs) and goldfish behavioral responses to polyamines were investigated in vivo . Electro-olfactogram (EOG) recordings indicated that polyamines (putrescine, cadaverine...
