When was the human sense of smell first linked to specific receptors?
Quick Answer
The molecular basis of smell was identified in 1991, when researchers Linda Buck and Richard Axel discovered odorant receptors.
The Full Story
In 1991, Linda Buck and Richard Axel identified a large family of odorant receptors, explaining how the nose detects smells at the molecular level. Their work showed that each receptor responds to certain odor molecules and that the brain combines these signals into distinct smells. This discovery transformed sensory biology and earned them the 2004 Nobel Prize in Physiology or Medicine. It also helped explain why humans can distinguish so many odors.
