ABSTRACT
Whether pheromone signaling exists in humans is still a matter of intense discussion. Emerging brain imaging studies suggest sexually dimorphic neuronal response to certain chemosignals, which, according to psychophysical data, possess pheromonelike properties. There are also indications that the neuronal response to these compounds depends on sexual orientation. Furthermore, our brain seems to be able to extract kin-specific signals, and processes body odors differently than other perceptually similar odors. Together, this data sheds new light on the chemosensory perception in humans and the implications thereof are discussed.
