The research, which showed rats’ preference for jazz while under the influence of a certain substance, was criticised by animal rights groups.
These are the results of a controversial 2011 study by Albany Medical College, in which scientists exposed 36 rats to ‘Für Elise’ by Beethoven and ‘Four’, a brassy jazz standard by Miles Davis. The rats overwhelmingly preferred Beethoven to Davis, but they liked silence best of all.
In the second part of the experiment, the rats were given cocaine and played Miles Davis over a period of a few days. After that, the rodents preferred the jazz even after the drug was out of their system.
The research, according to scientists, showed rats can be conditioned to like any music associated with their drug experience.
