Our latest paper in PLoS Biology was a great project. We show that the human olfactory system seems to code mainly odor perception (rated intensity), not physical properties (concentration). Fantastic work by @nordenneuro.bsky.social, @artinarshamian.bsky.social, Irene Zanettin, and Mikael Lundkvist

Excited to share our new paper in PLOS Biology!
We asked a simple question: when we perceive an odor as weak or strong, does oscillations in the human olfactory system represent the physical concentration of the odor, or our subjective perception of its intensity?

How can some smells seem stronger than others despite equivalent odor concentrations? @nordenneuro.bsky.social &co show that coordinated neural activity between #OlfactoryBulb & #PiriformCortex tracks how intensely an odor is perceived (rather than concentration) @plosbiology.org 🧪 plos.io/4fQxXR5
