Much information is conveyed to animals by the diverse molecules propagated in their environment. This information is transmitted and treated within the olfactory system to be utilized by the rest of the brain. In this process, the sensory flow arriving fr ...
Olfaction, the detection of odorous chemicals in the environment, is one of the oldest mammalian sensory systems and involves large number (up to 1000) of distinct G protein coupled olfactory receptors (OR). The chemical interaction of volatile molecules w ...
Optical imaging techniques offer powerful solutions to capture brain networks processing in animals, especially when activity is distributed in functionally distinct spatial domains. Despite the progress in imaging techniques, the standard analysis procedu ...
Olfaction and the olfactory pathway is a good system to study sensory processing in general, mainly because of the simplified organization of the cells constituting the olfactory bulb, the anatomical structure responsible for early odor encoding and proces ...
Optical imaging is a powerful technique to map brain function in animals. In this study, we consider in vivo optical imaging of the murine olfactory bulb, using an intrinsic Signal and a genetically expressed activity reporter fluorescent protein (synaptop ...

The olfactory system is a highly specialized chemodetector capable of discriminating between thousands of volatile chemical substances. This enormous capacity of chemical recognition is based on a large family of olfactory receptors (ORs). Despite the fact ...
The animal olfactory system represents the gold standard of olfactory biosensors with its capability to identify and discriminate thousands of odorant compounds. In order to mimic the performances of natural olfactory sensors it is necessary to develop met ...
BACKGROUND: Odorant receptors (ORs) are thought to act in a combinatorial fashion, in which odor identity is encoded by the activation of a subset of ORs and the olfactory sensory neurons (OSNs) that express them. The extent to which a single OR contribute ...
Odor perception may be considered from different perspectives: the physicochemical properties of odorants and target surfaces of interest, the biological aspects of electing odorant molecules by odorant receptors and their related downstream cellular signa ...
