Alarm pheromones are substances that send danger signals to different parts of the brain. When these signals are perceived by other pheromones of the same class, they can act as cues that alert humans or animals about a potential ...
The neural machinery underlying our olfactory sense continues to be an enigma for neuroscience. A recent review in Neuron seeks to expand traditional ideas about how neurons in the olfactory bulb might encode information ...
University of California, Berkeley, neuroscientists have discovered a genetic trigger that makes the nose renew its smell sensors, providing hope for new therapies for people who have lost their sense of smell due to trauma ...

Our sense of smell depends on the transmission of olfactory information from the nose to the olfactory bulb in the brain through the olfactory nerve. And without olfactory bulbs, smell isn't possible—or so scientists thought.
