New olfactory receptor mapping reveals systemic biases in neuroscience research on smell perception and receptor organization
Original framing: “First detailed 'smell map' reveals how noses track odours” — Nature
Cross-culturally, olfaction is not a uniform biological process but a diverse cultural and ecological interface. In Japan, the practice of 'kōdō' (the art of incense) treats smell as a meditative and aesthetic experience, while in India, Ayurveda uses aromatic plants for healing and balance. Western neuroscience, by contrast, often frames smell as a problem to be solved through technological intervention, such as electronic noses for industrial applications. These contrasting approaches highlight how olfactory perception is shaped by cultural values, economic systems, and historical contexts, challenging the universality assumed in mechanistic models.
This study’s revelation of olfactory receptor organization in mice, while framed as a breakthrough, exemplifies how Western neuroscience perpetuates epistemic injustices by prioritizing animal models and mechanistic frameworks over human and cross-cultural diversity.
The reliance on mice reflects a colonial legacy in science, where non-human animals are treated as universal proxies, sidelining the rich olfactory traditions of Indigenous and non-Western communities. Historically, sensory research has been shaped by Eurocentric biases, from Linnaeus’s odor classifications to the dominance of lab-controlled environments, which obscure the dynamic, culturally embedded nature of smell. A trickster’s lens reveals the absurdity of this framing: while mice receive detailed 'smell maps,' human olfactory diversity—shaped by genetics, culture, and spirituality—remains understudied. The path forward requires decolonizing olfactory research, integrating Indigenous knowledge, and developing technologies that honor the complexity of human perception. Actors such as Nature journal, funding agencies, and academic institutions must confront their role in perpetuating these biases and commit to collaborative, inclusive approaches that redefine how we understand and value the sense of smell.
