Single olfactory sensory neurons simultaneously integrate the components of an odour mixture

P Duchamp‐Viret, A Duchamp… - European Journal of …, 2003 - Wiley Online Library
Most odours are complex mixtures. However, the capacities of olfactory sensory neurons (OSNs)
to process complex odour stimuli have never been explored in air‐breathing vertebrates…

Peripheral odor coding in the rat and frog: quality and intensity specification

P Duchamp-Viret, A Duchamp… - Journal of …, 2000 - Soc Neuroscience
In mammals, two recent studies have shown recently that one odor molecule can be recognized

Odor response properties of rat olfactory receptor neurons

P Duchamp-Viret, MA Chaput, A Duchamp - Science, 1999 - science.org
Molecular biology studies of olfaction have identified a multigene family of molecular

Spiking frequency versus odorant concentration in olfactory receptor neurons

JP Rospars, P Lánský, P Duchamp-Viret, A Duchamp - Biosystems, 2000 - Elsevier

epithelium in response to four odourants applied at precisely controlled concentrations. A set of …

Odor processing in the frog olfactory system

P Duchamp-Viret, A Duchamp - Progress in neurobiology, 1997 - Elsevier
In the frog, unitary electrophysiological recordings have been extensively used to investigate
odor processing along the olfactory pathways. From the responses of primary second-order …
