It may sound like sci-fy,
\nbut mind reading equipment are much closer to become a reality than most people
\ncan imagine. A new study carried out at D\u2019Or Institute for Research and
\nEducation used a Magnetic Resonance (MR) machine to read participants\u2019 minds
\nand find out what song they were listening to. The study, published today in Scientific
\nReports<\/em><\/a>, contributes for the improvement of the technique and
\npave the way to new research on reconstruction of auditory imagination and
\ninner speech. In the clinical domain, it can enhance brain-computer interfaces
\nin order to establish communication with locked-in syndrome patients.<\/p>\n

In the experiment, six
\nvolunteers heard 40 pieces of classical music, rock, pop, jazz, and others. The
\nneural fingerprint of each song on participants\u2019 brain was captured by the MR
\nmachine while a computer was learning to identify the brain patterns elicited
\nby each musical piece. Musical features such as tonality, dynamics, rhythm and
\ntimbre were taken in account by the computer. <\/p>\n

After that, researchers
\nexpected that the computer would be able to do the opposite way: identify which
\nsong participants were listening to, based on their brain activity \u2013 a
\ntechnique known as brain decoding. When confronted with two options, the
\ncomputer showed up to 85% accuracy in identifying the correct song, which is a
\ngreat performance, comparing to previous studies.<\/p>\n

Researchers then pushed the
\ntest even harder by providing not two but 10 options (e.g. one correct and nine
\nwrong) to the computer. In this scenario, the computer correctly identified the
\nsong in 74% of the decisions.<\/p>\n

In the future, studies on
\nbrain decoding and machine learning will create possibilities of communication
\nregardless any kind of written or spoken language. \u201cMachines will be able to translate
\nour musical thoughts into songs\u201d, says Sebastian Hoefle, researcher from D\u2019Or
\nInstitute and PhD student from Federal University of Rio de Janeiro, Brazil.
\nThe study is a result of a collaboration between Brazilian researchers and
\ncolleagues from Germany, Finland and India.<\/p>\n

According to Hoefle, brain
\ndecoding researches provide alternatives to understand neural functioning and
\ninteract with it using artificial intelligence. In the future, he expects to
\nfind answers for questions like \u201cwhat musical features make some people love a
\nsong while others don\u2019t? Is our brain adapted to prefer a specific kind of music?\u201d<\/p>\n
