Notes and Sources

Being a dog emerged from conversations, interviews, classes, and experiences with dogs and people who work with or think about smell. On the person side, this includes Jonathan Ball, George Berger, John Buechsenstein, Noah Charney, Brent Craven, Annemarie DeAngelo, Bob Dougherty, Charley Eiseman, Stuart Firestein, Simon Gadbois, Avery Gilbert, Leta Herman, Pat Kaynaroglu, Raymond Matts, Alana McGee, Kate Mclean, Cindy Otto, George Preti, Kristin Rosenbach, Leslie Vosshall, and Sam Wasser.

lock and key theory of receptors:

This model is not without its detractors. Nineteenth-century models suggested that smell perception resulted from odor “undulations” or waves, as sound and vision perception do; in the twentieth century, Luca Turin elaborated this model and posited a vibrational theory of odor reception. (see Block et al. 2014. Implausibility of the vibrational theory of olfaction. Proceedings of the National Academy of Sciences, 112, e2766–e2774.)
