Singing from the same hymn sheet, but how?


Zebra finches

Songbirds learn to sing from a hymn sheet in their head, according to a new study. Swiss researchers writing in the journal Nature have pinpointed a region of the brain in Zebra Finches which they believe has an embedded recording of how the birds ought to be singing. A separate region apparently provides the birds with the know-how to identify mistakes in their songs. The research could also shed light on how humans learn to speak, according to scientists from Zurich University.

One interesting question to ask (though it’s doubtful it will be) is whether the human brain might also carry pre-sets for language. There have been many reported cases of head and other severe injuries leading to people switching from speaking their native language to another they’ve never spoken before, or been taught. In other cases people don’t switch language, but start speaking with a different dialect—someone from south-east England waking up to find themselves talking with a Scouse (Liverpudlian) accent, for example.
