We all think mice are a bit of a pest, but they are much more developed than we thought before. They communicate in ways that have shocked scientists and seem to have brain power that is making people reconsider their treatment of them. A recent study of mice offers new insights into the brain's workings.
The remarkable songs of these mice calling each other are very similar to our human conversations. There seem to be similar brain control clusters in these tiny mammals to brain control systems in humans that are responsible for language.
The study revealed that while one brain system directs the patterns of notes that make up songs, the other brain system controls duets with another mouse, according to Michael Long, a neuroscientist at New
York University's School of Medicine. This was a real surprise for them.
The mice call each other with repeating calls. Their duets are to attract mates and stake out territory. Two male singing mice create a rapid-fire duet. Once an animal calls, it's like a symphony that goes off.
Although the singing mice's brains are not exactly like the human brains, the areas that are used to pace chatter, give clues to the workings of human conversations.
The singing mice live high in the mountains of the Central American cloud forest. Their main diet consists of fresh insects, fruits and berries. The dark brown mice have a short tail and are infinitesimally tiny. An adult mouse weighs only about 12g, which is as much as a tablespoon of sugar!
