Document Summary
Olfaction is also extremely important in sexual reproduction because it triggers mating behaviour in many species. Menstrual synchrony: women who live together often have menstrual periods about the same time. Stern and mcclintock: experiment that led them to conclude that menstrual synchrony is caused by human pheromones. Anosmia: the loss of the ability to smell as a result or injury or infection. People suffering from anosmia describe the great void created by their inability to taste many foods because of the close connection between smell and flavour. Our sense of smell enables us to detect extremely low concentrations of some odorants. The detection threshold for odours is the lowest concentration at which an odorant can be detected. One trial contains a weak smell and the other no smell: threshold if 75% correct. There is a very large range of threshold.
