Using calcium imaging in the honeybee, we simultaneously measured the projection neuron output responses and a compound signal dominated by receptor neuron input in identified olfactory glomeruli to odours spanning seven log units of concentration. A comparison of the two processing levels indicates that the intercellular computation within the AL modulates and contrast-enhances the primary olfactory signals. As a result the AL network optimizes the olfactory code: odour representation is improved at lower concentrations, the relative activity of olfactory glomeruli allows encoding odour quality over up to four log-unit concentrations, and odour-intensity is reliably represented in the overall excitation across AL.</dcterms:abstract> <dc:language>eng</dc:language> <dc:creator>Sachse, Silke</dc:creator> <dcterms:bibliographicCitation>First publ. in: European Journal of Neuroscience, Vol. 18 (2003), pp. 2119-2132</dcterms:bibliographicCitation> <dc:contributor>Sachse, Silke</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:33:41Z</dc:date> <dc:creator>Galizia, Cosmas Giovanni</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:33:41Z</dcterms:available> </rdf:Description> </rdf:RDF>
