Electrocortical (EEG) correlates of music and states of consciousness
Neuropsychological Trends November 1, 2007 Lazar Skaric, Milorad Tomasevic, Dejan Rakovic et al.
Attempts to localize musical abilities in particular brain regions have largely failed, except for differences between musicians and non-musicians in hemispheric specialization and EEG correlations. Human emotional response to music depends on the limbic system, suggesting a possible neurobiological origin for music-induced altered states of consciousness, similar to those in Eastern yogic practices. In a group of 6 adults, 4 types of spiritual music were evaluated. The most prominent changes in theta or alpha frequency bands occurred in two subjects listening to Indian spiritual music, Bhajan.
