Cichy et al. show that trimethylamine (TMA), a gut microbiome-derived metabolite, activates the receptor TAAR5 in the main olfactory system to regulate aggression and social dominance in male mice. Th...

Although topographical maps organize many peripheral sensory systems, it remains unclear whether olfactory sensory neurons (OSNs) choose which of the ~1100 odor receptors (ORs) to express based upon t...

It’s time to fashion olfactory neuroscience stimuli based on odor concentrations in the wild, say study investigators Elizabeth Hong and Matt Wachowiak.

A study using flies of the genus Drosophila adapted to life in diverse thermal environments shows how evolution has shaped temperature preference by acting on both molecular heat receptors and th...

Sensory systems enable organisms to detect and respond to environmental signals relevant for their survival and reproduction. A crucial aspect of any sensory signal is its intensity; understanding how...
