摘要
There is a growing appreciation for the role of sniffing in the formation of the olfactory percept. With this in mind, monitoring and measurement of sniffing is an important aspect of olfactory experiments. There are several methods for measuring human sniffs concurrent with odor delivery in olfactory experiments. Here, we set out to compare the temporal sensitivity and power of these different methods by applying them all simultaneously with an olfactory task. We discuss the advantages and disadvantages of each method and conclude in recommending the use of a nasal cannula linked to a pressure sensor whenever possible.
