Fluid turbulence is a double-edged sword for the navigation of macroscopic animals, such
as birds, insects, and rodents. On the one hand, turbulence enables pheromone …

The biological olfactory system is the sensory system responsible for the detection of the
chemical composition of the environment. Several attempts to mimic biological olfactory …

INTRODUCTION The mammalian nose is arguably the best chemical sensor on the planet,
able to detect and discriminate among a large and diverse repertoire of mostly small …

Noses are extremely sophisticated chemical detectors allowing animals to use scents to
interpret and navigate their environments. Odor detection starts with the activation of odorant …

Most natural odors are complex mixtures of volatile components, competing to bind odorant
receptors (ORs) expressed in olfactory sensory neurons (OSNs) of the nose. To date …

Odor landscapes contain complex blends of molecules that each activate unique,
overlap** populations of olfactory sensory neurons (OSNs). Despite the presence of …

Sensory information is selectively or non-selectively enhanced and inhibited in the brain, but
it remains unclear whether and how this occurs at the most peripheral level. Using in vivo …

In color vision, the quantitative rules for mixing lights to make a target color are well
understood. By contrast, the rules for mixing odorants to make a target odor remain elusive …

Sensory systems are organized hierarchically, but feedback projections frequently disrupt
this order. In the olfactory bulb (OB), cortical feedback projections numerically match sensory …

Odor perception is first determined by how the myriad of environmental volatiles are
detected at the periphery of the olfactory system. The combinatorial activation of dedicated …
