That music playing in your head is a real conundrum for scientists

Researchers at EPFL can now see what happens in our brains when we hear music in our heads. The researchers hope that in time their findings will be used to help people who have lost the ability to speak.

When we listen to , different parts of our brain process different information – such as high and – so that our auditory perception of the sounds matches what we hear. It’s easy to study the of someone who is listening to a song, for instance, as we have the technology to record and analyze the neural responses that each sound produces as it is heard. It’s much more complicated, however, to try and understand what happens in our brain when we hear music in our heads without any auditory stimulation. As with analyzing real music, the brain’s responses have to be linked to a given sound. But when the music is in our heads, that sound doesn’t actually exist – or at least our ears don’t hear it. Using a novel approach, researchers with EPFL’s Defitech Foundation Chair in Human-Machine Interface (CNBI) were able to analyze what happens in our brains when we hum in our heads.

Bird caught in amber 100 million years ago is best ever found

Insects are not the only creatures that got stuck in amber during the time of the dinosaurs. Bits of ancient birds and dinosaurs have been found too – and now the most complete bird yet has been found.
