The olfactory system
The olfactory epithelium contains millions of olfactory neurons, which send messages directly to the olfactory bulb of the brain.
The olfactory receptor cells are the only neurons in the nervous system exposed directly to the external environment.
Their work and discoveries range from cancer therapy and laser physics to developing proteins that can solve humankind’s chemical problems. The work of the 2018 Nobel Laureates also included combating war crimes, as well as integrating innovation and climate with economic growth. Find out more.
