At this week’s Cognitive Neuroscience Symposium in San Francisco scientists think they have found the molecular basis of the Mozart effect. A study on rats showed a little more why listening to Mozart may be improving learning and memory test after listening to a Sonata by Mozart.

This Mozart effect was already discovered in 1993, but now there seems to be a scientific basis for it.

In this new study rats that listened to a Mozart sonata, compared to other music, showed higher levels of factors responsible for stimulating and changing the connections between brain cells.

For the scientists among us:

- increased gene expression of BDNF, a neural growth factor
- increased CREB, a learning and memory compound
- increased synapsin I, a synaptic growth protein

The research might be useful in developing (music) therapies. And of course help to understand what effects music, rhythms and sound structures can have on the brain.
