A microbiome-derived olfactory signal regulates inter-male aggression and social dominance in mice
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...

Finally, our results would not be possible without past and present members of the Datta lab, including Tatsuya Tsukahara (now at the LTRI in Toronto) and great collaborators like Martin Escamilla del Arenal and Tom Bozza (
@neuroboz.bsky.social
). We look forward to your feedback on this work!

A spatial code governs olfactory receptor choice and aligns sensory maps in the nose and brain
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...

Olfactory neuroscientists have known for a while that their stimuli stink. A new analysis illuminates the extent of the problem. By

Smell studies often use unnaturally high odor concentrations, analysis reveals
It’s time to fashion olfactory neuroscience stimuli based on odor concentrations in the wild, say study investigators Elizabeth Hong and Matt Wachowiak.

Glad to share this review of odor concentrations in nature versus experiments, just out in J Neurosci. Spoiler: they are far apart. We discuss implications for olfactory neuroscience and welcome debate. With
