Ants have evolved an acute sense of smell, which requires each sensory neuron to choose one scent receptor out of hundreds.

Olfactory receptor (OR) genes, representing the largest multigene family in mammalian genomes, have undergone extensive evolutionary modifications characterised by dynamic patterns of gene duplication ...

Humans have about 400 odorant receptors (ORs), but scientists have had trouble finding ligands that match up with most of ...

What neural and behavioral mechanisms allow mice to identify food sources, navigate toward them, and initiate consumption? A ...

Using data from both mice and humans, a Johns Hopkins Medicine research team has found that a cell surface protein that senses odors and chemicals may be responsible for - and help explain - sex ...

This paper presents a valuable theory and analysis of the role of neurogenesis and inhibitory plasticity in the drift of neural representations in the olfactory system. For one of the findings, ...

Firmenich International has patented a high-throughput assay system for identifying compounds that enhance olfactory receptor activity, intensifying the perception of target odorant compounds. The ...

The research article, “Ni-rGO Sensor Combined with Human Olfactory Receptor-Embedded Nanodiscs for Detecting Gas-Phase DMMP as a Simulant of Nerve Agents,” was published in ACS Sensors. Gas sensors ...
