Researchers have made a groundbreaking discovery that human olfactory perception can detect changes in odors within just a single breath, challenging the previously held view that our sense of smell is slow.
By utilizing a sniff-triggered device precise to 18 milliseconds, they demonstrated that people can discern between two different odors in sequences as short as 60 milliseconds—faster than a blink.
