Abstract

Timing as a factor in the sense of smell Olfactory systems encode smells not only by which neurons respond, but also by when they respond. In mice, sniffing a particular odour evokes a precise sequence of activity across olfactory neurons, but it is not known whether such timing information is actually read out and used. To test whether mice perceive the timing of olfactory activation relative to sniffs, Dmitry Rinberg and colleagues activated olfactory neurons using optogenetics. They find that mice can behaviourally report timing differences of as little as 10 milliseconds, and that such timing information is encoded in the olfactory bulb downstream.
