Stimulating someone’s brain with magnetic pulses is enough to change their taste in music – according to new research.
Using a non-invasive technique called transcranial magnetic stimulation – Scientists managed to change the enjoyment of music felt by their subjects.
The circuitry in question is found in a part of the brain called the left dorsolateral prefrontal cortex.
Previous brain imaging studies have demonstrated that stimulation of this region leads to the release of a substance called dopamine – which acts as a chemical ‘reward’.
Other studies have show that pleasurable music engages reward circuits in the brain.
But this is the first time anyone has manipulated this circuitry to change the way people think.
When the scientists used ‘excitatory’ stimulation on the target brain region the participants reported that they liked the music they were listening to more and when ‘inhibitory’ stimulation was used they liked it less.
