New form of animal communication discovered
Date:3/7/2013

Sniffing, a common behavior in dogs, cats and other animals, has been observed to also serve as a method for rats to communicatea fundamental discovery that may help scientists identify brain regions critical for interpreting communications cues and what brain malfunctions may cause some complex social disorders.

Researchers have long observed how animals vigorously sniff when they interact, a habit usually passed off as simply smelling each other. But Daniel W. Wesson, PhD, of Case Western Reserve University School of Medicine, whose research is published in Current Biology, found that rats sniff each other to signal a social hierarchy and prevent aggressive behavior.

Wesson, who drew upon previous work showing that, similar to humans, rodents naturally form complex social hierarchies, used wireless methods to record and observe rats as they interacted. He found that, when two rats approach each other, one communicates dominance by sniffing more frequently, while the subordinate signals its role by sniffing less. Wesson found that if the subordinate didn't do so, the dominant rat was more likely to become aggressive to the other.

Wesson theorized the dominant rat was displaying a "conflict avoidance signal," similar to a large monkey walking into a room and banging its chest. In response, the subordinate animal might cower and look away, or in the case of the rats, decrease its sniffing.

"These novel and exciting findings show that how one animal sniffs another greatly matters within their social network," said Wesson, an associate professor of neurosciences. "This sniffing behavior might reflect a common mechanism of communication behavior across many types of animals and in a variety of social contexts. It is highly likely that our pets use similar communication strategies in front of our eyes each day, but because we do not use this ourselves, it isn't recognizable as 'communication'."

Wesson's findings represent the first new form of communication behavior in rats since it was discovered in the 1970s that they communicate through vocal ultrasonic frequencies. The research provides a basis for understanding how neurological disorders might impact the brain's ability to conduct normal, appropriate social behaviors.

Wesson's laboratory will use these findings to better understand how certain behaviors go awry. Ultimately, the hope is to learn whether this new form of communication can help explain how the brain controls complex social behaviors and how these neural centers might inappropriately deal with social cues.
