Mice and rats have been staple creatures for laboratory research for nearly a century for good reasons: As human proxies for study, they share more than 97 percent of their DNA with our species. They also live shorter lives, have more babies, are cheaper to purchase and maintain and don’t need to sign waivers to give their lives to science. No wonder nearly 85 percent of the 25-million-plus lab animals used today are either rats or mice.
But despite their omnipresence in lab settings, rodent culture itself is still relatively understudied — especially the combination of chirping, bruxing and other behaviors that constitute rodent language. But a new software called DeepSqueak, outlined in Neuropsychopharmacology and developed by researchers at the University of Washington, could help demystify rodent language to better monitor how our furry analogs fare during experiments.
There’s more at stake for humans than just learning how to say “Hi” to Stuart Little in his native tongue. By cracking their communication, we stand to keep tabs on rodents less invasively and support research that depends on tracking their emotional states.
