• Example of a studied chemo signal?

  • Sources:

    An example of a studied chemo signal is the "smell of fear." This phenomenon refers to humans emitting a specific body odor when in a state of fear, which was first discovered in humans by Denise Chen. This chemo signal influences the physiology and behavior of other humans, illustrating how chemical signals play a role in human interactions 1.

    Another notable example involves emotional tears, which act as a chemo signaling mechanism. Research has shown that tears can influence human behavior and physiology. In one study, mouse pup tears were found to lower aggression in male adult mice, suggesting a protective mechanism 2.
