report that the piriform-to-olfactory bulb feedback in the mouse carries multimodal identity and reward contingency signals, which are re-formatted within seconds, according to behavioral context.

Research in my laboratory employs the experimentally tractable mouse olfactory system, which exhibits many of the types of experience-dependent developmental and adaptive changes that occur elsewhere ...

For the experiments, a human olfactory receptor (hOR1A1) was immobilized on a gold surface with an antibody to ensure its orientation and improve the sensitivity of the measurements.
