Amazing stuff!
"... In 2015, neuroscientists at MIT identified a population of neurons in the auditory cortex that responds specifically to music. In a new study that appeared today in the journal Current Biology, the same team of researchers led by Sam Norman-Haignere have identified specific neurons in the brain that light up only when we hear singing, but not other types of music. ..."
From the abstract:
"How is music represented in the brain? While neuroimaging has revealed some spatial segregation between responses to music versus other sounds, little is known about the neural code for music itself. ... The inferred components replicated many prior findings, including distinct neural selectivity for speech and music, but also revealed a novel component that responded nearly exclusively to music with singing. Song selectivity was not explainable by standard acoustic features, was located near speech- and music-selective responses, and was also evident in individual electrodes. These results suggest that representations of music are fractionated into subpopulations selective for different types of music, one of which is specialized for the analysis of song."
