An electronic nose is a device composed of an array of odour sensors with sensitivity to a wide range of chemical compounds.
Clouds of odours from various sources can overlap and lead to different perceptions.
Prior to conditioning, odours from each of the four 'cocktail' species were thawed and mixed together to form the 'cocktail' of odours containing an equal amount of odour from each species.
Finally, on the subject of odours.
Thus, we simply highlight that one set of odours reduced the behaviour and a different odour increased it.
This indicates that each reef has a distinct repertoire of odours and that fish have the ability to detect these different odours.
The electrical conductivity of these films varies in the presence of different chemicals, so that when the array of films is exposed to a particular odour, the different films respond in a characteristic way.Dr Subramanian's electronic nose, however, takes a different approach.
The NA-NOSE is an artificial olfactory system based on an array of highly cross-reactive gas sensors that can identify and separate different odours, even if the odorants are present at very low concentrations and their differences are very subtle (see Supplementary Figure S2, SOI).
