Resumen:
In the present contribution we review our understanding of musical emotion focusing in thehypotheses, approaches, and results obtained in our interdisciplinary group since 2001 whenan initial study proved that different musical excerpts evoke a significant inter-observeragreement in the selection of previously organized emotion terms within a relativelyhomogeneous population of human subjects. We have used both a correlation measure amongthe different EEG electrode sites and metabolic images of brain function in non-musicianhuman volunteers during the hearing of three instrumental music masterpieces selected fortheir capacity to generate pleasant or unpleasant music emotions. Using both fMRI and EEGcoherence brain images during the listening of the three masterpieces, we found that musicinducedemotions are sustained by an activation of specific brain sites and changes in thepattern of coherent activity between cortical regions. Both brain imaging approachesidentified divergent brain networks for positive and negative music affective valence. A leftcortical system involved with pleasant music feelings included the posterior temporal-parietal,occipital, and middle prefrontal regions. A coherent activity in upper alpha frequencies tookplace between most left hemisphere electrodes with a focus in the temporo-parietal andoccipital regions. In other studies we found that the coherent alpha activity of the lefthemisphere involved in pleasant music emotion is much larger in women linking all frontalregions with the left temporal and parietal-temporal association areas of the brain. Eventhough women and men reported similar levels of all emotions, the self-reported feeling ofbeing happy was only significant in women and the number of significant adjectives of thehappy component was more abundant in them. The predominance of left hemisphereactivation with pleasant musical feelings and right activation with unpleasant ones isconsistent with right hemisphere predominance for dealing with novel cognitive situations andthe left for predictable representations. The emotional effects of music may have to do withsymbolic and grammatical properties that engage representational semantic systems of themind/brain. The activations of extensive networks gain emotional meaning in higher neocortical substrata int
