The smell of fear: it’s dose dependent
Jasper de Groot published an article on the chemical communication of fear in the high impact journal Philosophical Transactions of the Royal Society B: Biological Sciences. His study shows that humans can express the quantity of their experienced fear in their body odor. That is, the more fearful a person was (induced by scary movie clips), the more odorant molecules that person emitted from the armpit region. Funded by a Niels Stensen Fellowship, this research was conducted at the University of Pennsylvania (Philadelphia, USA) in collaboration with professor Jay Gottfried and Peter Kirk.
